What are TubBlox?
TubBlox are a formwork which is made from expanded polystyrene. TubBlox kits allow the basic hot tub or pool to be constructed from simple blocks, strengthen it with steel reinforcement rebar & then fill them full of concrete. Think of “Lego for adults”!
This method is quick, easy and perfect for the DIYer.
The accessory pieces allow you to create almost any pool or hot tub shape imaginable. The TubBlox Kits have an insulation value which is much greater than traditional construction methods, leading to lower heating costs & savings on energy. In the current climate, it is really important that our DIY Hot Tubs and Pools are fully insulated to keep the running costs down.
