Manufactured here in the UK and made entirely from recycled polyolefin, our bases are Lloyds British tested to be able to withstand up to 420 tonnes per square metre. As well as being incredibly tough our bases are very easy to put down and can be done easily without any training thanks to its lightweight frame and simple to use slot and peg connection. Being made of plastic and with an open structure, each base is UV and weather-resistant so will not rot or break down as other foundations may and are permeable so any spilt water or rain can drain naturally away from your hot tub reducing the likelihood of water damage to your spa. Suitable for all types of spas, our bases are effective regardless of what is installed on top of them.

One of our major selling points is the fact that our base can be used across all makes and models so we don’t ignore any part of the spa market. This particular base size is perfect for all square hot tubs with a footprint of up to 231x231cm. You can see specific makes and models in our “compatibility” tab above, but if you do not see your hot tub mentioned, use the measurements provided to see if this base or another size would be a suitable foundation for your spa.

Can I use the plastic hot tub base panels under an inflatable hot tub.
We do not recommend this, as the plastic tub base panels can sometimes have sharp edges which may catch on the soft material and potentially damage the inflatable hot tub. We do have inflatable hot tub bases, which are perfect for supporting your blow up hot tub.
What sub-base do I need under my hot tub base?
We recommend you prepare the ground below your base with approximately 100mm of a compact hard base (type 1 or type 3), a weed-suppressing membrane and sand to level.
What is the difference between compact hard base type 1 or type 3?
Compact hard base, type 1 is much finer and can occasionally dust while the compact hard base, type 3 is larger and more permeable.
Can I put the base straight onto grass or soil?
We recommend not installing directly onto grass or soil but instead, install onto a compact hard base as it creates a sturdy, even base. Soil or grass can and will most likely will absorb water leading to sinking and creating an uneven sub-base for your spa base.
Can your plastic bases be installed on to concrete slabs/pads?
Yes, they can be installed onto concrete slabs or pads as long as the existing ground is strong and level. The base will allow airflow under your spa and elevate it away from any potential surface water.
How much gravel or aggregate should I use to fill my base?
Approximately 8kg of gravel or aggregate is required to fill each panel, or 72kg per m².
What size gravel should I use?
We recommend using anything up to 20mm in size.
Does the base need to be filled with gravel?
Our bases are more than strong enough without a gravel fill, able to withstand up to 420 tonnes per sqm. The gravel can be used to compact and enforce even more whilst also being a decorative finish.
Does this product come with pins or membrane?
Yes, our hot tub base kits come with pins and a sheet of membrane.
Can the plastic base panels be cut to size?
Yes they can be cut and we recommend doing so with a fine tooth saw.
Do I need pegs or anchors to secure my base?
Pegs and anchors to secure you base are only necessary when installing on areas which have a gradient over 12%.
How do I know which side of the panel to put down?
The bottom of the base has ‘X-Grid’ written on it, indicating the face you put on the ground.
Can the base panels be stacked on top of each other?
No, they are not designed to be stacked.
Where can I find installation instructions?
Install guides can be found on the ‘downloads’ tab. In addition, more information on installations can be found through our blogs and YouTube videos.
Can I create a grass base with the use of your hot tub base?
Yes, grass can grow in the panels cells when correctly filled with soil and seed.
Do your plastic hot tub bases have a warranty?
Yes, our bases have a 10 year manufacturer warranty.
Can I be guaranteed the same colour all throughout my product?
Our products are new generation, manufactured entirely from post-consumer recycled plastic; this means you may occasionally find very slightly different shades of colour.
