How to Renovate a Bathroom

Bathrooms are often one of the smallest rooms in the house and also one of the most expensive to renovate. This is why many people leave their bathroom renovation to last or put it off for another day. Many houses still have tried old bathrooms in need of a full bathroom renovation, from the 50s through to the 80s that are past there used by date.

In this example we will take you through a major bathroom renovation of a 1950s house bathroom. As you can see below this bathroom was well passed its used by date and water was entering the next room. Also this house did not have a hot water tank it had a 1950s instant hot water service and it was dangerous, oh what a bathroom! The shower had not worked for years and old bath needed to be renewed. In fact there was nothing in this old bathroom that could be used again for the new bathroom

Step one: Bathroom design

- Consider the design for the space you have available. In our example an older lady lives in the home and easy access to the shower and bathroom fittings was a must. So we decided to add a new toilet, wider window for light and change the position of the bathroom vanity. Another bathroom design consideration was to only have flick mixers so the water would be easy to turn on and off thus traditional bathroom taps were eliminated. We were able to extend the old bathroom by one metre, so this was part of the bathroom design adding a walk in shower and a cavity siding door.

Step two: Bathroom Renovation - Demolition

We removed everything from the old bathroom, all remaining bathroom tiles, old bathroom fittings, the bath and all the old bathroom taps and plumbing. Because of the age of the house we knew that the wall linings had asbestos in them so we put on all our safety gear and removed this into an asbestos bin.

Step three: Bathroom Renovation - Plumbing

- We had planned the bathroom renovation out and so the first thing to do was to extend the old bathroom space by 1 metre, and then re-plumb the whole bathroom. New copper pipe was put into place with the in wall flick mixers in place. Any new electrical wiring was also roughed in ready to be wired to the mains later. At this point we also added a new bathroom window at the end of the bathroom after removing the two old timber windows.

Step four: Bathroom Renovation - Wall linings

- Install the bath and re-line the walls with 6mm villa board and nail in place every 150mm. Care must be taken not to nail into a water pipes.

Step five: Bathroom Drainage and Waterproofing

- Make sure that all bathroom drain pipes are in place and ready for the bathroom vanity, bath, toilet, and shower to be connected. Then water proof the whole room to 100mm up the walls except in the shower where you must waterproof up 2100mm minimum high.

Step Six: Bathroom Renovation - Wall and floor tiling

- Tile the complete room. Floor tiles first and then wall tiles on top of this. For more on laying ceramic tiles check out our pages on ceramic tiling. When we laid the bathroom floor and wall tiles, we also inserted an aluminium channel to hold the shower screen glass. Next grout all tiles using a quality bathroom grout with mould fugicides added.

Step Seven: Bathroom fittings and fixtures

- Install your bathroom vanity and fixtures making sure that they are all sealed and all connecting pipes are not leaking. Test everything and then add your bathroom lighting and do a final clean.
