Large hot tubs for six, eight or more people

How big is a large hot tub?

Seat counts are a guide, not a promise. A tub “for eight” seats eight adults upright and close together; for regular use with legroom, most groups are happier one size up from their usual headcount. Compare the inside diameter or inside length, because that is where people sit, and the outside dimension, because that is what has to fit the base and the access route.

Round tubs in our range run up to large diameters with an internal or external heater, and the square models offer generous straight benches. Our hot tub dimensions guide explains how to read the sizes, and the 8 person hot tubs and 6 person hot tubs pages go into each capacity.

Heating a big tub

More people means more water, and more water takes longer to heat. On a large tub the heater choice matters more than on a two-seater:

• External wood-fired stove: keeps the seating area clear of a stove guard, so every seat is usable, and makes refuelling easy.
• Internal or integrated stove: compact and efficient, but it takes up part of the bench; see log burner hot tubs.
• Electric or hybrid: holds temperature for frequent use; a qualified electrician confirms the supply.

A well-fitted hot tub cover makes a real difference on a large water surface, both while heating and between sessions.

Base, access and delivery

A large tub filled with water and people places a heavy, concentrated load on the ground, so the base must be engineered for it: a reinforced concrete slab or a properly designed paved or framed base, level and drained. Follow the base preparation guide and, for decking or roof terraces, ask a structural engineer.

Measure the delivery route before ordering. A large round tub travels in one piece, so gates, side passages and overhead cables all need checking, and you may need lifting equipment.

Who buys a large hot tub?

Large families, households who host friends, holiday lets and glamping sites. For commercial use, plan for more frequent water changes, filtration and a clear routine for cleaning and supervision; the water care guide is a good start. If the group is usually four, a 4 person hot tub heats faster and costs less to run. All models are on the outdoor hot tubs page.

What a large hot tub costs to run

Running costs grow with the water surface and the number of sessions. A wood-fired tub costs what your logs cost; an electric or hybrid tub depends on your tariff and on how long you keep the water hot. On any large tub the three biggest savings are a well-fitted insulated hot tub cover, closing it as soon as everyone is out, and a sheltered spot out of the wind. Starting prices for every model, inc. VAT, are on hot tub prices.

Water care for a big group

More bathers bring more sweat, sun cream and body oils into the water. A wood-fired tub without filtration is usually drained and refilled more often; with a sand filter, UV-C and a regular treatment routine the water stays clear for longer. Shower before bathing, keep the cover on between sessions and test the water regularly. Our water care guide explains filtration, testing and when to change the water.

Hot tubs for ten to twelve people

For ten or more, look at the biggest round diameters and the large square models, or consider two tubs side by side, one wood-fired and one cold plunge, which often works better for groups than one very large tub. Holiday lets and glamping sites should also plan for hard-wearing steps, a non-slip surround and a clear cleaning routine between guests.

Ordering and delivery

Each tub is made to order and delivered by lorry, fully assembled. Unloading is the customer’s responsibility and a large tub needs a forklift, HIAB or crane, so check access before you order. The delivery page and the purchase process explain lead times, payment and the delivery day. Large tubs already installed by our customers are on the reviews and project map page.
