Core insights: When a bath–shower combo is the right choice
Why choose a bath and shower combination?
- Maximise floor space in small bathrooms while retaining a full bathing option.
- Great for family homes, guest bathrooms and rentals where versatility matters.
- Cost-effective compared with adding a separate shower enclosure.
Benefits and common pitfalls
- Benefits: space efficiency, lower plumbing costs, flexible use, easier heating and ventilation.
- Pitfalls to avoid: slippery bases, splash issues without the right screen, insufficient waterproofing, and poor tap/shower placement that causes cold drips.

Materials and finishes that work in WA
Bathtub options for a shower for tub setup
- Alcove/built-in baths: Best for a shower in a bathtub; the tiled wall and an over-bath screen contain spray well.
- Back-to-wall baths: Clean look; ensure a compatible over-bath screen and correct fall to waste.
- Inset baths with tiled hob: Practical for kids and seated showering; specify a non-slip finish.
Over-bath screens and curtains
- Frameless or semi-frameless glass screens: Minimal visual bulk; choose toughened safety glass and consider a swing panel for easier cleaning.
- Quality curtain + rail: Cost-effective and flexible in tight spaces; use weighted hems and mould-resistant fabrics.
Tiles and slip resistance
- Floor tiles: Choose a slip rating suited to residential bathrooms (P2–P3). Porcelain tiles are durable and low-porosity for WA homes.
- Wall tiles: Ceramic or porcelain with mould-resistant grout (epoxy grout is a premium option).
Tapware and fittings
- Install a combined bath spout and rail shower or a twin shower set. Position mixer controls to avoid cold water drips.
- WELS-rated products reduce water and energy use—great for family bathrooms and rentals.
- Consider a practical niche shelf and a grab rail (stylish options exist) for multi-generational safety.
Vanity tops and cabinetry
Match your bathroom aesthetic to your broader home—many clients echo their shaker kitchen profile in vanity fronts or repeat kitchen finishes in the bathroom for a cohesive look across kitchen renovations Perth, bathrooms, laundries and walk-in wardrobe zones.
| Surface | Pros | Considerations | Typical Use |
|---|---|---|---|
| Engineered stone benchtop (legacy installs) | Hard-wearing, premium look, stain resistant | Note: New fabrication/installation of crystalline-silica engineered stone is prohibited in Australia. Existing tops can be retained during renovations. | Existing kitchens/vanities being refreshed |
| Porcelain / Sintered stone | Heat, stain and UV resistant; low maintenance; excellent for wet areas | Requires experienced fabrication; premium price bracket | High-end bathrooms and kitchens |
| Laminate benchtop | Budget-friendly, wide design range, quick to install | Not as heat/impact resistant; seal edges well in wet zones | Cost-conscious bathrooms and laundries |
Regulatory note: Engineered stone containing crystalline silica is banned for new fabrication/installation in Australia. See government guidance via WA Building and Energy or Safe Work Australia. For alternatives, our designers recommend porcelain/sintered stone or solid surface. Refer to Building and Energy (WA) for updates.

Two quick Perth case examples
Case 1: Floreat family bathroom
A family needed a bath and shower combination without sacrificing storage. We specified an inset bath with a semi-frameless screen, a niche shelf, and a shaker-profile vanity echoing their kitchen renovations Perth. The porcelain vanity top and soft-close drawers simplified cleaning. Result: Safe, splash-controlled bathing for kids and a stylish adult shower experience.
Case 2: Fremantle apartment ensuite
Space constraints called for a back-to-wall bath with a pivoting frameless panel. We increased ventilation, selected P3 slip-rated floor tiles, and used handleless cabinetry to visually expand the room. The cohesive finishes linked seamlessly with the client’s open-plan living and compact laundry fit-out.

- Agree on finishes that tie in with your kitchen, laundry and wardrobe colours.
