Hot tub decking across Camden — Camden
Hot Tub Decking in Camden is a specific brief for us — homeowners installing a hot tub who need the deck sized to carry the loaded weight. The default local answer isn't a stock catalogue drop: it's 150×47mm C24 joists at 300mm centres over doubled bearers under the tub footprint; hot-tub area calculated to 400kg/m² loaded. On Camden sites we also spec around listed-building and conservation constraints across most postcodes — timber and painted profiles only at the front, which is where a lot of hot-tub decking jobs quietly fail two years in. Recent work on Mansfield Road and Chetwynd Road. We orient jobs off Regent's Canal towpath. Chetwynd Road CA4 front picket. Painted softwood picket on oak posts, drawings submitted with the party-wall notice. Approved without amendment; matched the four-plot street line.

How we build hot-tub decking in Camden
150×47mm C24 joists at 300mm centres over doubled bearers under the tub footprint; hot-tub area calculated to 400kg/m² loaded. On Camden jobs we adjust for listed-building and conservation constraints across most postcodes — timber and painted profiles only at the front.
Property mix locally: Georgian and Victorian townhouses in Primrose Hill and Hampstead, plus dense terraces around Kentish Town and Gospel Oak. Typical gardens: small walled courtyards behind period houses; several conservation areas restrict visible materials. Postcodes we regularly service: NW1, NW3, NW5, N7, WC1.
Where hot-tub decking isn't the right answer
- — very large commercial-spec spas that need a poured slab, not a timber deck
- — properties with no access for delivery of a filled tub after the deck is complete
Hot Tub Decking FAQs — Camden
Composite or hardwood for a hot-tub surround?
On hot-tub decking jobs in Camden (NW1), our default answer is: 150×47mm C24 joists at 300mm centres over doubled bearers under the tub footprint; hot-tub area calculated to 400kg/m² loaded.

What board grooving do you recommend for grip?
Across Camden we spec around listed-building and conservation constraints across most postcodes — timber and painted profiles only at the front, so on hot-tub decking that usually means Trex or Q-Deck composite for a wet, chlorinated environment. For context: grooved composite boards keep grip when wet — the whole point of a hot-tub deck surface. Hardwood and composite specified to genuine service-life numbers.
