Thermal cover or wooden lid?
The thermal cover has a UV-resistant synthetic-leather outer over 70 mm insulation, with fixing straps and a locking system. It is the better choice if you heat often, keep the water in for several days or use the tub through winter, because it reduces heat loss from the water surface while the tub heats and between sessions. Colours are black (RAL 9005), anthracite grey (RAL 7016) and dark brown (RAL 8016).
A wooden lid matches the timber of the tub and keeps debris out. It is a separate option on the same product page, offered for 1,800 mm tubs (with an integrated or external heater, or with an internal heater), 2,000 mm tubs and square tubs to your dimensions. Confirm its construction and fit in the quotation.
Getting the right fit
A cover only works if it matches the tub. Four thermal-cover configurations are priced directly:
| Configuration | Tub size |
|---|---|
| Round tub, integrated or external heater | Ø1,800 mm inside / Ø2,000 mm outside |
| Round tub, internal heater | Ø1,800 mm inside / Ø2,000 mm outside |
| Large round tub, integrated or external heater | Ø2,000 mm inside / Ø2,250 mm outside |
| Square tub | to the dimensions you provide |
The finished round covers are Ø2,000 and Ø2,250 mm. For any other TimberIN model, or an existing tub, we make the cover by quotation: send the model, measurements and photographs so the shape and cut-outs for the heater and chimney can be checked before manufacture.
Replacing a hot tub cover
Covers wear out. Signs it is time for a replacement include a cover that no longer sits flat, torn or faded outer material, water soaking into the insulation, or straps and locks that no longer hold. Our blog explains how to inspect a hot tub cover. When you order a replacement for a TimberIN tub, give the model and order details if you have them; for another brand’s tub, measure carefully and send photographs.
Our covers are designed for TimberIN tubs. If you have an acrylic spa from another maker, check the shape, radius of the corners and skirt before asking for a quote.
Using and caring for the cover
- Keep the cover on while heating to shorten the wait and on between sessions to hold the heat.
- Fasten the straps and lock when the tub is not in use, especially with children around.
- Brush off snow and standing water, and lift the cover off evenly rather than dragging it.
- Wipe the outer with mild soapy water; avoid solvents.
- Keep the cover clear of the chimney and stove when a wood-fired heater is lit.
