All of which is crucial for protecting underlying materials from water damage and preventing costly repairs in the future.

  • Toilets: While not always essential for water containment, sealing toilet bases and fitments can make cleaning much easier and improve the overall look.
  • Sinks and Countertops: Sealing the gaps where the sink meets a countertop or the wall prevents water from seeping underneath and causing damage to cabinets.
