Baths Over 1700mm Buying Guide


The step up to 1800mm and beyond makes a genuine difference to comfort rather than a marginal one. That extra length is enough to let taller people, or anyone who simply prefers more room, lie flat and fully submerged, rather than compromising with knees bent or one end of the body left out of the water. These baths also carry a stronger visual presence in a room, generally reading as the space's clear design feature rather than one fixture among several.

Where a large bath works well

Master ensuites commonly become the space for a large bath, since the room is already intended as a private retreat, and generous soaking room reinforces that purpose directly. Main family bathrooms benefit from the extra splash room during bath time for younger children, while still functioning as a properly comfortable bath for adults once the household has settled for the evening. New builds and full renovations offer the most flexibility for this size, since the layout can be planned around the bath from the outset rather than fitting one into an existing footprint.

Types of large baths

Freestanding baths at 1800mm and above make the strongest design statement, standing independently and needing genuine floor clearance both for visual impact and ease of cleaning. They pair naturally with floor-mounted tapware.

Back-to-wall baths offer much of that same sculptural profile on three sides while sitting flush against the wall on the fourth, removing the dust-collecting gap a fully freestanding bath leaves behind it, and saving a small amount of floor space in the process.

Built-in baths sit within a tiled frame, or hob, giving a practical tiled ledge for shampoo, candles or bath toys alongside the tub. An 1800mm built-in bath delivers the extra soaking length within a tidy, space-efficient configuration.

Corner baths make efficient use of an awkward layout, and at a larger size often include a moulded seat, giving a surprisingly generous amount of usable internal space from what might otherwise be an underused corner.

Island baths take the built-in concept further, set into a large tiled platform standing away from every wall. The surrounding platform offers ample space to sit, or to arrange towels and plants, and the whole configuration reads as a genuinely grand centrepiece.

Spa baths add integrated massage jets to the equation, and the extra length at this size gives enough room to lie back fully while the jets work, rather than needing to compromise on position to reach every jet.

Choosing a shape

Rectangular baths remain the classic, space-efficient choice, with clean lines suited to almost any bathroom style. Oval baths bring a softer, more organic feel, generally freestanding and well suited to a calmer, spa-like atmosphere. Round baths make the boldest statement, often deeper than a standard tub for a fuller, more immersive soak, though they need genuine floor space to accommodate the shape. Slipper baths, with a high, sloping back at one or both ends, give excellent support for reading or relaxing, carrying a vintage-inspired silhouette that still reads as contemporary. Square baths bring a sharper, more architectural character suited to a minimalist bathroom, and fluted baths add textured, grooved exterior detailing for a more considered visual finish.

The genuine benefits of going larger

Comfort is the primary reason to choose a larger bath: lying flat and fully covered by water, rather than compromising with bent knees, matters considerably for taller users and is a genuine improvement for anyone. Shared use becomes practical rather than a logistical challenge, letting two people bathe together comfortably where a standard-sized tub wouldn't allow it. Visual presence is also a real factor, since a large, well-chosen bath tends to become the room's clear focal point, changing how considered the whole space feels. Many larger baths are also deeper than standard sizes, which supports a more thorough, effective soak for tired muscles.

Brands in this collection

Caroma brings long-established Australian quality. Decina focuses on acrylic and spa bath comfort specifically. Fienza delivers on-trend, modern design at an accessible price point. Kaskade Stone specialises in premium stone baths. ADP offers Australian-made quality with a strong design focus. Bao Bath is known for simple, elegant shapes and considered stone designs. Turner Hastings suits a more classic, English-influenced style. BelBagno brings European and Italian design flair. Clark rounds out the range with dependable, practical options.

Completing the bathroom

A large bath is easiest to plan alongside the room's tiling and tapware, since both installation type and finish depend on decisions made elsewhere in the renovation. The Blue Space's Tiles and Tapware collections are worth reviewing alongside a bath selection to bring the full bathroom together.

Frequently Asked Questions

What is the largest bathtub size available?

Baths over 1700mm are generally the largest standard category, with some freestanding models extending to 1800mm or slightly beyond. Past that point, sizing tends to move into made-to-order or specialist territory rather than standard stocked ranges. A longer bath needs a genuinely larger bathroom to avoid crowding the rest of the room, so it's worth measuring the full floor plan, not just confirming the tub itself will physically fit.

What is an oversized bathtub usually called?

There's no single industry term. You'll see them marketed as "large baths," "long baths," "over 1700mm baths" or occasionally "double-ended baths" if the shape allows two people to sit facing each other. The description on the product listing (exact length, width and depth) is a more reliable guide than the marketing name, since usage varies between brands.

Why choose a bath longer than 1700mm?

The main reasons are user height and how the bath will be used. Taller adults often find anything under 1700mm restrictive for a full stretch-out soak, and a longer bath also suits households that want a deeper, more generous soak rather than a quick bath. It's a genuine trade-off against floor space, so it tends to suit larger bathrooms or ensuites purpose-built around the bath rather than a retrofit into an existing small footprint.

Does a large bath need extra floor support?

A full-sized bath holds a substantial volume of water, and once you add an adult's body weight, a standard bath in use can exceed 200kg, more for a longer, higher-capacity model. Most ground floor slabs handle this without issue, but timber-framed upper floors should be checked by a builder or engineer before installing a large bath, particularly in an older home. This is a structural question for a qualified tradesperson, not something to estimate by eye.

What size bathroom suits a bath over 1700mm?

As a practical minimum, allow enough floor area for the bath itself plus clearance on the accessible sides for stepping in and out safely, along with normal room circulation. If your bathroom is on the smaller side, a shorter bath in the 1500 to 1700mm range or a space-efficient shape is usually the more workable option. See small baths for that end of the size range.

Can a large bath still be fitted with a shower over it?

It's possible on some models, but the extra length can affect where the screen or curtain needs to sit and how the fall to waste is set out underneath. That's a separate set of considerations from bath size alone, covered on the shower over bath page.
