1. Figure out if you need to transfer the toilet or other plumbing fixtures
Relocating plumbing fixtures will add to the workaround time for the renovation. Not to mention the costs and the hassle it brings to your daily routine. For example: transferring a toilet requires refitting the pipes. The plumber must also ensure the refitted pipes don’t mess with the floor’s foundation. Apart from the pipes, the vents must also be moved or changed. The bathroom walls may need to be taken out for proper positioning of the vent.
As what you have read, moving plumbing fixtures require a lot of time, effort, and money. You need to evaluate if it’s necessary to transfer the plumbing appliances. It doesn’t hurt to have professional consultation from an experienced plumber.
