St Marys is a well-established Sydney suburb with a strong community feel and a diverse mix of housing styles. Many homes in the area were built between the 1960s and 1990s, alongside newer infill developments. Unique Bathrooms has been transforming bathrooms across St Marys and the wider Penrith City Council area for over 20 years.
Local homeowners are increasingly choosing to renovate rather than move. Popular upgrades include modernising outdated layouts, improving storage, adding better lighting, and creating more functional spaces for families and busy professionals. Whether you’re after a budget-friendly refresh or a complete luxury renovation, our team delivers exceptional results on time and on budget.

If you are weighing up a bathroom renovation in St Marys, the useful first question is not what it costs but what it involves. Moving a toilet or shower changes the plumbing and the price; keeping fixtures where they are keeps both contained. We set out both options when we quote in St Marys.
Design Direction
Pattern is returning to St Marys bathroom floors after a long stretch of plain tile, through terrazzo, honed marble-look porcelain and encaustic-style patterned tiles used as a defined zone. Keeping pattern on the floor and quiet finishes on the walls tends to age better than the reverse. For genuine stone, sealing and ongoing maintenance need to be discussed up front - marble in a main family bathroom will show wear that porcelain simply will not.
Relocating a toilet or shower in a St Marys bathroom means new drainage falls, and depending on whether the floor is a slab or a timber subfloor that ranges from straightforward to significant. It is worth it when the current layout genuinely fails - a door that fouls the vanity, a shower you cannot stand in properly, a toilet visible from the hallway. It is not worth it for a marginal gain, and we will tell you which one you have.
To an extent. Trades run to a sequence that cannot be reordered - you cannot tile before the membrane cures. We can work around access constraints and, in St Marys apartments, around strata-mandated work hours, and we give you the program up front so there are no surprises.
Yes. A bathroom that ignores the rest of the house tends to look like an afterthought. We work to the era and character of your St Marys property - period-appropriate detailing in an older home, cleaner contemporary lines in a newer one - rather than applying the same look to every job.
Yes. Strip-out, removal and disposal are included in your fixed St Marys price, including the old fixtures and tiled substrate. Skip placement is arranged with you beforehand, which matters on narrower streets and for St Marys apartment work where access has to be booked.

Extraction is the single most neglected element in St Marys bathroom renovations and the one most likely to ruin the result. An undersized fan, or one ducted into the roof cavity instead of outside, produces mould on new paintwork within a season. We size extraction to the room volume, duct it externally, and where the budget allows run it on a humidity sensor or timer so it continues after the room is vacated.
The difference between a good and an average St Marys bathroom is usually visible only at fit-off. Tiles cut to land symmetrically at corners and niches. Silicone lines that are straight and the right colour. Waste and tap holes drilled centrally. Grout colour chosen to suit the tile rather than defaulting to white. None of it costs materially more, all of it is a function of care, and collectively it is what people notice without being able to name.
Part of quoting honestly in St Marys is advising against things. Retiling over existing tile when the membrane underneath is unknown. Moving a toilet for a marginal layout gain. Natural stone in a high-traffic family bathroom where it will not be maintained. Spending the budget on fittings while leaving inadequate extraction. We would rather lose the upsell than warrant a room we know will disappoint.
