What Makes It Different

While most wood-fired tubs use a contoured base built for sitting upright, the Flat Bottom range does away with that shaping entirely — here's why that matters

Key features

The Flat Bottom range trades the built-in seating step for a completely flat floor — one simple change with a big effect.

Flat Floor, Natural Seating

No moulded seating ledge — stretch your legs out and sit low and level, closer to how you'd sit in a bath than perch on a bench.

Less Water, Faster Heat

A lower tub holds around 350 fewer litres than our standard-height models, so the wood-fired stove brings it up to temperature sooner.

Fits Through Tight Spaces

At 72 cm tall, it passes through narrow side gates and passageways that a standard-height tub often can't — no fence removal, no crane.

A Wood-Fired Hot Tub Sized for Small Families

Some tubs are made for two, like the ofuro, others for larger groups of 4–6. The Flat Bottom range sits comfortably in between — sized around small families who use their tub often

The Right Size for 3–4

Designed to seat two adults with one or two children, this size reflects the specific needs of a small family.

More Sociable Than an Ofuro

Compared to an ofuro, which seats only two, the Flat Bottom is larger — enough room for one or two children too.

More Intimate Than a Crowd Tub

Compared to our 4–6 person Round Classic, built for larger groups, the Flat Bottom keeps things closer and more personal — ideal for quiet family time rather than hosting a crowd.

A More Natural Way to Sit

Easier to Watch Over

At 72 cm tall, the water sits noticeably lower than in a standard tub, which many parents find reassuring when bathing with younger children — you can see and reach them more easily. As with any hot tub, children should always be supervised by an adult while in or near the water.

Adjustable Door Latch, Built-In Airflow Control

The stove door hook catches on one of several notches — choose a closer or farther position to leave a small gap that fine-tunes airflow and helps control the burn

Steps? Usually Not Needed

Most customers step straight in — no stairs needed. Steps change the process: you sit down first, then swing your legs in, rather than stepping in from standing. Given the low height, steps can sometimes make entry more awkward, not less — worth trying without them first.

Tub, Stove & Filter, as One

The round stove mounts close to the tub, and the optional round filter box matches — every piece designed as a set.

Compact by Design

Lower height means the tub sits low and unobtrusive in the garden — a cleaner, more modern look that doesn't block sightlines.

Frequently asked questions

How many people fit in a flat bottom tub?

Comfortably 3–4 — for example, two adults and one or two children.

Is it safe for young children?

The lower water level makes it easier to supervise children closely, but as with any tub, adult supervision is required at all times.

Do I need steps to get in?

Most people don't. Steps are available as an optional accessory for anyone who finds it uncomfortable to lift a leg over the rim.

Will it fit through my side gate?

Its low height gives it a much better chance than a standard tub, but always measure your narrowest access point before ordering.

How much water do I need to fill the tub?

Approximately 890 litres.
