We get a lot of questions about placing hot tubs in UK gardens. Here’s everything you need to know to do it safely and properly.
Can decking hold a hot tub?
Yes, but only if it’s built correctly. A filled hot tub with people can weigh over 1,500kg. Our guide how heavy are hot tubs breaks it down by size. Your decking needs strong structural support underneath.
Best practices for decking installations
- Use reinforced joists or add extra supports under the spa area
- Check with a builder or structural engineer if unsure
- Ensure the decking surface is completely level and does not flex under weight
Not sure which tub suits decking? Explore our 4 person hot tubs. Many are designed specifically for garden decking. Check the footprint in our guide to hot tub sizes and dimensions.
Can you put a hot tub on grass?
No. Grass won’t support a hot tub safely. Over time it will shift, become muddy, or uneven, leading to damage (especially to the spa’s base and plumbing).
Better base alternatives
- Concrete slabs (most durable)
- Compacted gravel with a firm frame
- Plastic spa pads or modular ground decks
For freestanding setups, check our hot tub range. These pair perfectly with a solid base without needing to be sunk into the ground.
Extra tips for outdoor hot tub placement
- Leave access for maintenance and cleaning
- Keep space for the cover to open/close fully
- Check safe reach to your power supply (our guide to plug and play vs 32 amp hot tubs explains the options)
- Plan drainage in case of overflow or splashes
