1500mm to 1700mm Baths Buying Guide
This size range earns its "standard" label because it fits the widest range of Australian bathroom footprints without either cramping the room or leaving a bath too short to use comfortably. It's the size most new builds are planned around from the outset, and the most common replacement size in a straightforward bathroom renovation where the existing layout isn't changing significantly.
Choosing within the range
1500mm suits bathrooms with a more modest footprint, giving genuine soaking comfort without demanding the floor space a longer bath needs. 1600mm sits as a middle option, worth considering specifically for taller household members who find 1500mm slightly restrictive without needing to jump to the largest size available. 1700mm gives the most generous depth within this standard range, suited to a bathroom with a little more room to spare, or a household prioritising a longer, more relaxed soak as a daily habit rather than an occasional one.
Measuring the available space carefully, including door swings and any fixed fittings nearby, before choosing between these three lengths avoids a mismatch that only becomes obvious after the bath has arrived.
Styles within the size range
Freestanding baths in this range make a genuine visual statement, finished on all sides and suited to a bathroom with enough clearance to appreciate the shape from multiple angles. Back-to-wall baths offer much of that same sculptural look while sitting flush against one wall, a more space-efficient configuration that also simplifies cleaning, since there's no gap behind the tub to collect dust. Built-in baths, set into a tiled surround or hob, remain the most straightforward and space-smart option, particularly well suited to a family bathroom needing a stable, practical tiled edge nearby.
Materials and durability
Baths in this range are available in acrylic, stone resin and enamelled steel, each offering a different balance of weight, heat retention and price. Acrylic remains the lightest and most accessible option, stone resin gives the most substantial feel and best heat retention at a higher price point and weight, and steel offers exceptional durability with a distinctive, classic character. Whichever material is chosen, quality construction at this size matters for long-term comfort, since a bath this size sees genuinely frequent daily use rather than occasional soaking.
Design considerations
A bath in this size range is generally chosen after the bathroom's overall style direction is settled, since its shape and finish need to sit comfortably alongside the surrounding tiling, vanity and tapware rather than working against them. A sleek, minimal freestanding shape suits a contemporary bathroom, while a softer, more sculptural profile suits a bathroom leaning toward a warmer, more considered material palette. A practical built-in configuration suits a busy family bathroom prioritising function and a stable tiled edge over a strong sculptural statement.
Choosing the right size for your bathroom
If the available footprint is tighter than this range allows, The Blue Space's under 1500mm baths collection covers more compact options suited to smaller ensuites and apartments. For a larger bathroom or a genuinely luxurious soaking experience, the over 1700mm baths collection offers more generous sizing. To compare sizes, styles and materials across the full range in one place, the complete bathtubs collection is worth browsing before making a final decision.
Completing the bathroom
A bath in this size range is easiest to plan alongside the room's tiling and tapware, since installation type and finish both 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.
