That will depend on how old your plumbing and electrical currently are in your home or commercial building. Typically, things like plumbing and electrical get replaced every 20-25 years.
Luckily, any of our bathroom installers can check that your plumbing and electrical are up to code and confirm whether it needs to be updated or is suitable for another certain number of years. That would allow you to save money or direct those funds elsewhere to things like tiles or fixture upgrades.
