Can my deck, balcony or floor take a hot tub?
A filled hot tub with bathers commonly exceeds two tonnes over a small footprint. Our assessment looks at the structure you plan to put it on and identifies whether the loading is plausible or needs strengthening.
What the assessment covers
- • Proposed location: ground slab, timber deck, balcony, roof terrace, internal floor
- • Filled weight, footprint and resulting pressure on the supporting structure
- • Deck joist spans, bearers and post spacing, or slab thickness and sub-base
- • Access, drainage, and how the load reaches the ground
What you send us
- • Photos of the intended location, including underside of the deck if reachable
- • Hot tub model, dry weight, water capacity and dimensions
- • Deck or slab construction details and approximate spans
- • Whether the structure is at ground level or elevated
What you receive
- • Indicative risk level and confidence rating
- • Budget range for any strengthening work
- • Watch points: point loads, deflection, water ingress, edge distances
- • Whether a structural engineer's check is needed before delivery

Frequently asked questions
Is a normal garden deck enough?
Standard domestic decking is designed for people and furniture, not a concentrated two-tonne load. Additional posts, closer joist centres or a dedicated slab are common outcomes.
What about a balcony or roof terrace?
Elevated structures are the highest-risk case and almost always require a chartered structural engineer to check the existing capacity before installation.
