What you invest in your new space will be largely determined by your choice of fittings and finishes. As a guide, done well with the correct materials, a bathroom will generally start from $30,000 for a full renovation, which includes waterproofing, plumbing, electrical, and your selected bathroom fixtures and fittings such as tiles, vanities, toilets and showers.

Cheaply priced building work should be approached with caution, as the main variables are the materials used and the amount paid to the tradespeople doing work such as electrical and waterproofing.Keep in mind that a bathroom done correctly by responsible tradespeople could potentially save you a lot of money down the track.
