  • Enhances daily comfort and wellbeing.
  • Increases property value by up to 5–10% (RICS & estate agent data).
  • Differentiates your home in competitive areas like Kensington, Mayfair, Chelsea, and Notting Hill.

For many homeowners, a luxury bathroom becomes both a personal retreat and an investment strategy.
