Yes, you can technically put any toilet in, but a few things can make the job more involved and subsequently more expensive than if you were to choose a like-for-like toilet:
- Outlet position – if the new toilet’s outlet doesn’t line up with your existing waste pipe (P-trap vs S-trap), extra work is needed to adapt it.
- Rough-in measurements – wall-hung or back-to-wall styles often need different in-wall or floor spacing than a standard close-coupled toilet.
- WELS rating – it still has to meet the minimum 3-star water efficiency rating required under WA plumbing regulations, so old or non-compliant models are out.
- Floor and fixing type – older homes with a toilet concreted into the floor (like the Viveash job) need extra work before any new suite goes in, regardless of which one you pick.
