Key Takeaways
- Layout and fixture choices can affect plumbing, electrical work and waterproofing details.
- Product dimensions and installation information should be available before work begins.
- Plan for the period when the bathroom cannot be used.
A bathroom is a small room with a lot of building work packed into it. Plumbing, electrical work, ventilation, waterproofing, fixtures, storage and finishes all need to fit together.
The easiest place to begin is with the problems in the existing bathroom.
How should the bathroom work?
Think about who uses the room, when it is busiest and what is difficult now. A family bathroom, ensuite and accessible bathroom may need very different layouts.
Ask practical questions:
- Is there enough clear floor space?
- Can doors and drawers open without clashing?
- Is storage easy to reach?
- Does the shower keep water where it belongs?
- Is the room warm and well ventilated?
- Who needs support, seating or easier access?
Keeping or changing the layout
Keeping fixtures in similar positions can reduce some service changes, but it is not always the best answer. A poor layout may be worth changing if it improves access, storage or daily use.
The existing floor construction and plumbing access affect what can be moved. These details should be checked before a final layout is promised.
Choose fixtures with installation in mind
Product dimensions matter. Baths, vanities, toilets, tapware, mirrors, lights and cabinets need to work with the room and with each other.
Keep current product information for the items selected. It helps the builder and trades understand fixing, service and clearance requirements.
Waterproofing and ventilation
Wet-area work needs to follow current building requirements and the approved project documents. Junctions, falls, penetrations and transitions at doors need attention before tiles hide the work.
Ventilation should suit the room and how it is used. Moisture problems are harder to solve after ceilings, paint and joinery are complete.
Plan the sequence
A bathroom is normally unavailable for part of the renovation. If it is the only bathroom, decide how the household will manage before demolition starts.
The order usually brings together removal, repairs, services, wall and floor preparation, waterproofing, finishes, fixtures and final checks. Product availability can affect the sequence, so confirm important items early.
What affects the quote?
Price is influenced by the existing condition, access, layout changes, plumbing and electrical work, fixture selections, tile size and pattern, cabinetry and any repair work found after removal.
Give each builder the same plan and selection information. If an item is still undecided, make sure the allowance is easy to identify.
