A bath is one of the most impactful bathroom renovation choices, significantly affecting both the feel of the space and the property’s appeal to future buyers. Understanding the plumbing requirements for different bath types helps you plan your renovation correctly.
Types of Baths for Melbourne Homes
Alcove (built-in) baths: The standard rectangular bath set into a three-sided alcove. The most common in Melbourne homes. Typically 1500-1700mm long. Easy to waterproof and tile around. Filler and overflow connect to concealed pipework in the wall or floor.
Freestanding baths: Increasingly popular in Melbourne renovations. Stand independently in the bathroom space. Floor-mounted or wall-mounted filler tap (no rim holes). The drain connects through the floor via a floor waste. Requires careful positioning relative to the drain and supply pipes.
Spa baths: Include in-built jets powered by a pump and motor. Require an electrical connection in addition to plumbing. The motor must be in a ventilated accessible space. More maintenance required than standard baths.
Bath Plumbing Requirements
Every bath requires: hot and cold water supply (to the mixer or separate taps), a waste fitting and overflow connection, and a drain connecting to the building’s drainage system. Freestanding baths require the floor waste to be precisely positioned before tiling. The plumber must know the exact bath model and its drain outlet position before setting the rough-in. This is why choosing the bath before the plumbing rough-in is essential in a renovation.
Bath Installation Costs in Melbourne
Like-for-like alcove bath replacement (same position) costs $350-$600 for plumbing labour. Freestanding bath installation (new floor waste position, floor-mounted filler tap) costs $500-$900 for plumbing. Spa bath installation adds $200-$400 for the motor plumbing connection (electrical connection separate). These costs cover plumbing only — the bath itself, tiling around it, and any wall or floor work are additional.
