Should I choose a freestanding or built-in tub for a NB bathroom renovation?

For most New Brunswick bathroom renovations, a built-in alcove tub is the practical choice — but a freestanding tub can be the right answer if your bathroom layout, budget, and lifestyle support it. The decision comes down to four factors: available floor space, plumbing configuration, cleaning preferences, and how much of your renovation budget you want to allocate to a single fixture.

Built-in alcove tubs are the workhorse of NB bathrooms for good reason. They fit into a three-wall surround, typically in a 60-inch standard footprint, and double as a shower with a curtain or glass enclosure above. Installation is straightforward — plumbing rough-in is contained to one end wall, the surround protects three walls from moisture, and the overall footprint is efficient. A standard acrylic alcove tub runs $400-$900 for the fixture itself, with full installation including tiling the surround running $3,500-$8,000 depending on tile selection and whether plumbing needs to be moved. For families with young children, the tub-shower combo is essentially irreplaceable.

Freestanding tubs have become increasingly popular in NB master bathroom renovations, and they can be genuinely stunning in the right space. The tradeoff is real, though. You need a minimum of 60-70 square feet of bathroom floor space to make a freestanding tub look intentional rather than crammed. The plumbing rough-in is more complex — the floor supply and drain must be positioned precisely beneath the tub, which means your plumber needs to know the exact tub placement before rough-in is finalized. Freestanding fixtures range from $800-$5,000+ for the tub alone, and a floor-mount freestanding faucet adds another $400-$1,500. Total installation including plumbing work typically runs $5,000-$12,000.

NB-Specific Considerations

NB's humidity swings matter here. With indoor humidity ranging from 20-30% in winter to 60-70% in summer, the gap between a freestanding tub and the floor is a moisture trap. That floor perimeter needs to be sealed properly and cleaned regularly — standing water that migrates under a freestanding tub against a wood subfloor is a mould problem waiting to happen. Built-in tubs with properly tiled and caulked surrounds are more forgiving of NB's humidity cycles when maintained correctly.

If your bathroom is in an older NB home — pre-1980 construction is common across Fredericton, Saint John, and Moncton's established neighbourhoods — confirm your subfloor can handle the weight. A cast iron freestanding tub filled with water can exceed 500 lbs. Acrylic freestanding tubs are lighter but still require a solid, level subfloor. If there's any bounce or softness in the floor, address that before choosing your fixture.

Practically speaking, if you're renovating a main family bathroom, go built-in — it's more functional, easier to maintain, and leaves more budget for quality tile work and fixtures. If this is a master ensuite with generous square footage and you're after that spa-bathroom aesthetic, a freestanding tub can be a beautiful centrepiece — just budget properly for the plumbing rough-in and make sure your TSANB-licensed plumber is involved in the planning before any floors are opened up.

For either choice, budget a 15-20% contingency on your bathroom renovation — NB's older housing stock regularly reveals surprises behind walls and under floors once demolition begins. A mid-range NB bathroom renovation runs $15,000-$30,000, and a full gut renovation with layout changes reaches $30,000-$50,000.
