“Hot tub” on a listing tells you almost nothing. After 25 years and 100,000+ group bookings at our sister brand Butlers in the Buff, we can tell you the difference between the weekend where the tub made the trip and the weekend where it caused a diplomatic incident comes down to five questions asked before booking — not after. This is the buying checklist. (For where to book and what tubs cost by region and season, see our hot tub houses guide.)
1. Match seats to group size
The single most common mistake: a 6-seater tub for a group of 16. That is not a hot tub, it is a rota war — someone ends up scheduling half-hour slots like a leisure centre. Our rule after watching thousands of groups: aim for seats equal to at least half the group. Sixteen people need an 8-seater or two tubs; our average activity group is 16, so this is not a fringe case.
2. Ask when it was drained and refilled
A properly managed tub is drained, cleaned and refilled between stays. Ask the owner directly: “When is the water changed?” A good owner answers instantly; a vague answer tells you everything. This is the least glamorous question on the list and the most important one.
3. Wood-fired or electric?
Wood-fired tubs are romantic and cheap to run, but take 3–4 hours to heat — someone has to start the fire at 4pm for an 8pm soak, every day. Electric tubs are kept always-hot between uses. For a party weekend, always-hot wins; for a slow cabin week, the ritual of the wood-fired tub is half the charm. Know which you are getting.
4. Confirm it is in the price
Some properties list the tub prominently and then charge a £100–£200 “heating and servicing” extra at checkout (illustrative figures — but we have seen both). Confirm in writing that the tub is included in the quoted price. It is one of the checks in our questions to ask before booking.
5. Check the quiet-hours rule
Tubs after 10pm are the #1 neighbour complaint at group houses — sound carries astonishingly far across a quiet valley at midnight. Most houses now write a tub curfew into the terms; know it before you plan the midnight soak, because breaching it is the fastest way to lose a deposit.
Five questions, five minutes, and the tub becomes the best thing about the weekend. Start with our houses with hot tubs and ask away.
