Set of 4 Square Concrete Planters – Onyx Garden Pot Set for Patios, Entrances & Indoor Styling
Create a coordinated plant display with the Cubrosa 4-piece square concrete planter set in Onyx Dusk. Designed for customers who want their garden, patio, balcony or indoor greenery to feel more styled and intentional, this matching planter set gives you four sizes in one bold, architectural finish.
Use all 4 together as a statement garden cluster, style them as a 3-and-1 arrangement, place them in pairs around a doorway, or split the set between indoor and outdoor spaces for a connected look throughout the home. The matching square shape and deep Onyx Dusk colourway make it easy to create a designer-style planter display without having to source separate pots that may not work together.
The charcoal black-grey finish adds strong contrast against green foliage, grasses, herbs, shrubs and seasonal planting. Whether used to frame an entrance, soften a patio corner, add structure beside outdoor seating, or bring compact greenery indoors, the Cubrosa set gives you flexibility, balance and a premium concrete look in one complete collection.

- Ideal for patios, balconies, entrances, garden rooms, courtyards, decking areas and indoor spaces

How to Style the Cubrosa 4-Piece Set
Use all 4 together as a statement cluster – Place the full set together in a patio corner, beside garden seating, near bifold doors, around a garden room or at the edge of a terrace. The different sizes create natural height variation, while the matching Onyx finish keeps the display clean, coordinated and premium.
Create a 3-and-1 arrangement – Style the 55cm, 40cm and 30cm pots together outdoors as the main garden feature, then use the 20cm pot indoors for herbs, succulents or compact houseplants. This gives your indoor and outdoor spaces a linked design theme without needing every pot in the same place.
Frame an entrance or walkway – Use the larger planters either side of a door, gate, patio opening or garden path, then position the smaller pots nearby to soften the layout. This helps create a more welcoming, considered entrance without needing built-in landscaping.
Split the set between home and garden – The set does not need to be used entirely outside. Use the 55cm and 40cm planters outdoors for statement planting, then bring the 30cm and 20cm pots indoors for kitchen herbs, hallway greenery, sideboard styling or shelf plants.
Style in pairs for balance – Use two larger pots to anchor a patio, doorway or seating area, while the two smaller pots add detail to tables, steps, ledges or indoor surfaces. This is ideal if you want symmetry without everything looking too formal.
Create a modern planter row – Line the pots along a patio edge, balcony wall, decking area or garden boundary. The square shape gives the display a neat, architectural look and helps define zones without building permanent borders.
Planting Ideas by Pot Size
| Pot Width | Best For | Suggested Use |
|---|---|---|
| 20cm | Herbs, succulents, compact houseplants and small decorative greenery | Windowsills, shelves, garden tables, kitchen counters, side tables and balcony ledges |
| 30cm | Lavender, herbs, grasses, flowering plants and medium houseplants | Patios, balconies, entrances, indoor corners, plant stands and grouped displays |
| 40cm | Ornamental grasses, seasonal planting, compact shrubs and mixed plant displays | Patio corners, garden rooms, decking areas, courtyards and entrance styling |
| 55cm | Feature shrubs, larger grasses, statement greenery and more substantial planting | Garden focal points, entrance framing, patio anchors, terrace styling and outdoor statement displays |
Why Choose the Cubrosa Planter Set?
A complete planter display in one purchase – Finding separate plant pots that work together can be difficult. The Cubrosa set solves that problem by giving you four matching square concrete planters in different sizes, making it easier to create a balanced, coordinated display from the start.
Designed to look intentional, not mismatched – Many gardens and patios end up with a mix of plastic pots, odd colours and different shapes collected over time. Cubrosa creates a more considered look, with matching proportions, a consistent Onyx Dusk finish and a premium concrete texture across all 4 pots.
Flexible indoor and outdoor styling – You are not limited to using the full set in one place. The larger pots can create structure outside, while the smaller pots can be used indoors for houseplants, herbs or shelf styling. This makes the set especially useful for homes with patios, balconies, garden rooms, open-plan kitchens or indoor-outdoor living spaces.
Bold Onyx Dusk colourway – The Onyx Dusk finish brings together deep charcoal, black and grey tones for a contemporary look that works beautifully with green foliage, pale stone, timber decking, black garden furniture, modern interiors and minimalist outdoor schemes.
Perfect for garden clustering – A cluster of different-sized planters is one of the easiest ways to make a patio, courtyard or garden corner feel styled. The 55cm planter acts as the anchor, while the 40cm, 30cm and 20cm pots add layers, height variation and planting detail around it.
Great for entrances and patio zones – Use the set to frame a front door, define an outdoor seating area, soften a paved corner, add structure beside bifold doors, or create a feature around a garden room. The square shape gives the display a neat, architectural look that feels more designed than standard round pots.
Useful across the seasons – Fill the pots with herbs and bright flowers in spring and summer, ornamental grasses and foliage in autumn, or evergreen shrubs and seasonal displays in winter. The neutral Onyx tone works throughout the year and allows the planting to take centre stage.
Premium pigmented concrete – Each Cubrosa planter is made from pigmented concrete, meaning the colour is part of the material rather than a painted surface. This helps prevent peeling or flaking and gives each pot a more authentic stone-like finish.
Durable, substantial and stable – The concrete construction and generous wall thickness give the planters a reassuring, premium feel. The larger sizes add useful visual weight outdoors, while the smaller pots remain practical for indoor and tabletop styling.
Solves the “plastic pot” problem – Lightweight plastic pots can look temporary, mismatched or unfinished. The Cubrosa set gives your plants a stronger visual base, helping even simple greenery feel more styled, permanent and high-end.
Matching saucers available for smaller sizes – For indoor use, matching saucers are available separately for the 20cm, 30cm and 40cm pots. They help catch excess water, protect surfaces and make the planters look more complete when used inside the home.
Easy to mix with existing garden furniture – The charcoal black-grey colour pairs well with rattan, timber, stone, concrete, black metal furniture, pale render, decking and modern outdoor tiles. It is bold enough to add contrast but neutral enough to work with many garden styles.
Where to Use the Cubrosa Set
Patios & terraces – Use the full set to bring structure, greenery and height variation to paved areas, especially where there are no built-in borders or planting beds.
Balconies & compact outdoor spaces – Split the set across corners, ledges and seating areas to add greenery without overwhelming the space.
Front doors & entrances – Use the larger planters for symmetry and impact, with the smaller pots adding detail on steps or beside the doorway.
Garden rooms & bifold doors – Place the set outside a garden room, studio or open-plan kitchen to soften the transition between indoor and outdoor living.
Indoor plant styling – Use the smaller planters indoors for herbs, succulents, houseplants or decorative greenery. Pair with matching saucers where available to help protect surfaces.
Courtyards & modern gardens – The square shape and dark Onyx finish work especially well in contemporary, urban, minimalist and architectural garden schemes.
Practical Notes
The Cubrosa planters are designed for indoor and outdoor use, with drainage holes included to support healthier root systems. For indoor placement, we recommend using suitable surface protection and pairing the smaller sizes with matching saucers where available.
For outdoor use, place planters on a stable, level surface and avoid allowing excess water to sit underneath the pot for long periods. More detailed advice can be found in our Pots & Planter Care Guidelines section at the bottom of this page.
Full Description
The Cubrosa 4-piece square concrete planter set in Onyx Dusk is designed for customers who want a coordinated, premium and flexible way to style plants across the garden and home. With four matching sizes included, this set makes it easy to create a complete planter display without trying to match separate pots from different ranges, colours or materials.
The set includes 20cm, 30cm, 40cm and 55cm square planters, giving you a useful mix of compact styling pots, medium planters and a larger 115L statement pot. Use them together as a layered outdoor cluster, split them into a 3-and-1 arrangement, style them in pairs, or place them across different areas of the home and garden for a connected look.
The Onyx Dusk colourway gives the Cubrosa set its bold, contemporary character. The deep charcoal, black and grey tone creates strong contrast against green foliage, grasses, herbs, flowers and shrubs, making the planting stand out while keeping the overall display refined and modern. It works beautifully with pale stone, concrete patios, black-framed doors, timber decking, garden furniture and neutral interiors.
One of the biggest advantages of buying the Cubrosa set is styling flexibility. The full 4-piece arrangement can create a strong focal point in a patio corner, courtyard, entrance or garden room setting. Alternatively, the larger 55cm and 40cm pots can be used outdoors for statement planting, while the 30cm and 20cm pots can be used inside for herbs, succulents or houseplants. This makes the set ideal for customers who want their indoor and outdoor spaces to feel connected rather than separate.
The square shape gives the planters a clean, architectural look that feels more structured than traditional round pots. It makes them especially effective when used beside entrances, along patio edges, around outdoor seating areas or in modern garden designs where neat lines and balanced proportions matter.
Each planter is made from pigmented concrete, giving it a durable stone-like finish where the colour runs through the material rather than sitting on the surface as paint. This helps prevent peeling and flaking while maintaining the raw concrete character, subtle pitting and handcrafted variation that give each pot its own natural finish.
The different sizes also make planting easier to plan. Use the 20cm pot for herbs, succulents or small houseplants; the 30cm pot for lavender, flowering plants or medium greenery; the 40cm pot for ornamental grasses, compact shrubs or seasonal displays; and the 55cm pot as the main anchor for larger feature planting.
For indoor styling, matching saucers are available separately for the 20cm, 30cm and 40cm pots. These help reduce watering mess, catch excess water from the drainage holes and protect shelves, floors, tabletops and windowsills. The 55cm planter does not have a matching saucer, making it best suited to outdoor feature placement or indoor areas where appropriate surface protection is used.
Designed for year-round versatility, the Cubrosa set is sealed, UV-stable and frost-resistant, making it suitable for outdoor use as well as indoor styling. For best results, follow the detailed advice in the Pots & Planter Care Guidelines section at the bottom of this page, including guidance on positioning, drainage, soil preparation, plant selection, frost protection and indoor surface protection.
Whether you want to upgrade a patio, frame an entrance, soften a balcony, style a garden room, or bring a more coordinated look to your indoor and outdoor planting, the Cubrosa 4-piece planter set in Onyx Dusk gives you a complete, flexible and premium solution. Strong, simple and easy to style, it turns everyday greenery into a more intentional design feature.
Choose options







Our pots are crafted from pigmented concrete and intentionally celebrate the beauty of raw, natural materials. Each piece features unique variations—subtle discoloration, small pits, fine crevices, and delicate hairline cracks and markings —that develop as part of the curing process. These imperfections are what give every pot its own character and charm, ensuring no two are ever exactly alike.
Measure First
Ensure the pots will fit through all access points, including doorways, gates, and pathways.
Consider the Weight
Many of our pots are heavy - some over 100kg - and are delivered on a pallet to the kerbside only.
You may need special equipment or assistance to help move your pot to their final location.
Inspect on Delivery
Check your items immediately upon arrival. Please take photos or videos when unwrapping to document any potential damage.
Handle With Care
Cutting the security straps of the item confirms acceptance. Once opened, full refunds are no longer available.
Returns Policy
We accept returns of unopened, undamaged items. Costs of return delivery will be deducted from your refund which can be up to £100 depending on location.
Larger Items
- Larger items are delivered palletised to kerbside via a specialist carrier.
- We require a solid, flat surface to safely unload using a pump truck.
- Delivery is to ground-level only and cannot be made on steep inclines.
- Please ensure your delivery location is accessible and level to avoid delays.
Positioning & Surface Protection
- Place on a level surface: Ensure your planter is positioned on stable, level ground to prevent tipping or uneven weight distribution.
- Use rubber feet or pot risers: Elevate your planter slightly with rubber feet or spacers. This improves drainage, prevents waterlogging, and protects the surface underneath from staining or damage.
Drainage & Soil Preparation
- Create a drainage layer: Fill the bottom 10% of the pot with drainage materials such as gravel, broken terracotta, or even clean plastic bottles. This encourages water flow and prevents root rot.
- Avoid overfilling with soil: Fill your planter 80-90% full with high-quality soil or compost. Leave room at the top to allow for watering and mulch if needed.
Tree & Plant Selection
- Choose suitable species: Only plant trees and shrubs that are suitable for container growth. Select species with compact or non-invasive root systems to avoid cracking or damaging the pot over time.
Weather Protection
- Frost protection in winter: Although our planters are sealed and frost-resistant, we recommend protecting them during extreme winter conditions. Use breathable covers or move planters to a sheltered location to prevent frost damage.
Indoor Use
- Seal around drainage bung if needed: For indoor placement, we suggest sealing around the temporary drainage bung before filling to prevent leaks. Use silicone or a waterproof sealant if required.
- We advise placing the pot on rubber pot feet or a rubber mat to protect floors
