Please check this general description of the steps involved in a bathroom renovation:
Planning and design: First things first, you gotta plan and design what you want. Figure out your budget, what you want to change, and how you want your new bathroom to look. You might want to work with an interior designer, bathroom designer or contractor to make sure you're on the right track.
Demolition (strip-out): Next up is the demolition or strip-out phase. Depending on how much you're changing, you might need to tear out the old shower, bathtub, toilet, vanity and other things in the bathroom.
Structural changes: If you're making structural changes, you might need to move plumbing or electrical stuff, or even add or remove walls.
Waterproofing: Waterproofing is super important to prevent water damage. You'll need to apply a waterproofing membrane or coating to the walls, floor and ceiling. There are a few different ways to do it, so choose what works best for your project.
Installation of new fixtures and finishes: Once the room is prepped, it's time to install the new fixtures and finishes. This might include a new shower, bathtub, toilet suite, vanity, and tiles for the walls and floor.
Finishing touches: After the big stuff is done, it's time for the finishing touches. You might want to install LED lighting, a ventilation system, and extra hooks and towel rails.
Cleanup and final touches: Last but not least, it's time to clean up and make any final adjustments or touch-ups to the bathroom. Get rid of any leftover construction rubbish and give it a final clean to make it look spick and span. Just like that!
