Whether you’re working with a compact powder room in an older Toronto home or planning a primary ensuite in Vaughan or York Region, a bathroom renovation isn’t just about new finishes — it’s about a layout that finally works. We manage every stage, from planning and material selections through construction and final finishing.
From compact bathrooms in older Toronto homes to primary ensuites and family bathrooms throughout Vaughan and York Region, our team manages every stage of the renovation—from planning and material selections to construction and final finishing.
Depending on your space and goals, your bathroom renovation might include:
A beautiful bathroom starts long before the finished tile is installed. Proper preparation, waterproofing, drainage and careful tile planning create the foundation for everything that follows.
At Star Builders, we put the same attention into what you don’t see as the finishes you do.
The most important parts of a shower are often the ones you never see.
We build our showers using Schluter prefabricated shower bases and KERDI waterproofing membrane to create a complete waterproofing system behind the finished tile.
Careful attention is given to seams, corners, niches and plumbing penetrations before tile installation begins.
Our Schluter systems are installed by a professional who has completed hands-on training through Schluter Systems’ Innovation Workshop.
Curbless showers require careful planning of the existing floor structure, drain location, slope and waterproofing.
Depending on the existing framing, the subfloor may need to be lowered or recessed to create enough depth for proper drainage while maintaining a flush transition into the bathroom.
We can also build custom steam showers, tiled ceilings, wall-to-wall niches and other specialized shower configurations.
Great tilework is planned before the first tile is installed.
Before installation, the substrate is carefully prepared to create a flat, stable surface while maintaining level where existing conditions allow.
Every tile layout is planned in advance so grout lines, niches, fixtures, corners and transitions align and flow naturally throughout the space. Tile sizes and starting points are considered ahead of time to minimize awkward cuts and create a balanced finished installation.
Proper installation techniques, mortar coverage and tile-levelling systems help achieve consistent joints and a flat, clean finished surface.
Our tilework isn’t limited to standard layouts. Depending on the design, we can incorporate custom details throughout the shower and bathroom while planning them as part of the overall tile layout.

Our shower assemblies use Schluter components and are installed according to Schluter requirements, allowing eligible installations to benefit from Schluter’s applicable system warranty.
Older Toronto homes often mean compact layouts, aging plumbing, limited ventilation, and floors that are no longer level. Homes across Vaughan, Richmond Hill, and York Region tend to have more space to work with, but need real planning to turn that space into a functional ensuite or family bathroom. We assess the existing conditions before construction starts, so the plan is built around your home — not a standard template.
Updating aging plumbing, electrical systems, ventilation and inefficient layouts while working with the existing character of the home.
Creating functional family bathrooms, modern ensuites and layouts designed around the needs of busy households.
From compact powder rooms to complete primary ensuite renovations, every project is planned around the home and homeowner.
A bathroom renovation lives or dies behind the tile — waterproofing mistakes don’t show up until months or years later. Here’s what you’re actually getting with us.

The cost of a bathroom renovation depends on the size of the space, existing conditions, layout changes, material selections and level of finishes. Custom showers, plumbing relocations, heated floors and structural modifications can also affect the overall budget.
