About The Plastic Hot Tub Base

Made of recycled plastic and manufactured in the UK, our eco-friendly bases are designed with an interlocking slot and peg system that makes laying the foundation incredibly easy. As the base is made from 100% recycled plastic, it is UV and weather resistant so unlike more traditional bases, ours will not rot or break down over time meaning there will be no maintenance or replacement costs in the future. Whilst being easy to lay and eco-friendly our bases are also very strong, when our base was tested by Lloyds British they confirmed out it could withstand up to 420 tonnes per square metre which is amazing. Another advantage of our base is that due to the open structure, any rain or excess water from the spa can drain away naturally which means there is less chance of stagnant water next to your hot tub or spa that could lead to external water damage.

Installation Guide

Can I use the ‘hot tub base panels’ under the inflatable hot tub.

We do not recommend this, as the ‘hot tub base panels’ can sometimes have sharp edges that can catch on the soft material of the inflatable hot tub.

What do I need under my grid?

We recommend you prep the grid with compact hard base (type 1 or type 3), sand and membrane.

Do I need pegs?

Only areas that have a gradient over 12% need pegs.

How do I know which side to put down?

The bottom of the hot tub base panel has ‘X-grid’ written on it, indicating the face you put on the ground.


How many grids are there per pack?

In each pack there are 4 grids.

How will order be sent?

Our X-Grid Panels are 33cm x 33cm. For ease, speed, and efficiency of shipping, we pack a maximum of 24 panels inboxes and send through courier network. Greater quantities than 180 panels will be delivered through the Palletways network.

How are the products packaged?

We take great care when packaging your order to ensure that our products reach you in the best possible condition. In addition, we are always trying to be more sustainably friendly therefore try to minimize the amount of plastic packaging we use around our products and use recycled packaging. If your product arrives broken, we will send replacements within 3-5 working days.

Can I be guaranteed the same colour all throughout my product?

Our products are new generation made entirely from post-consumer recycled plastic; this means you may occasionally find specs of different shades of colour.

What is the pricing of shipping based off?

Our shipping is based on the postcode and weight of the order. You can see the price of your shipping before you purchase by going into the checkout and filling in ‘calculate shipping’. We endeavor your product to be delivered within 3-5 working days.

Where can I find the instructions?

Instructions can be found on the ‘downloads’ tab at the bottom of the product’s page. In addition, more information on installation can be found through our blogs and YouTube videos.

Does this come with pins or membrane?

It comes with neither pins or membrane, you will need to buy this separately.

Do the hot tub base panels need gravel or is it strong enough without it?

The hot tub base panels are strong enough without gravel. The gravel can be used to compact and secure even more and for decorative use.
