Baths Over 1700mm

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.
