Many hotels groups have dabbled in modular building through the use of prefabricated bathrooms, which are built in a factory environment where temperature, light and humidity are controlled.

“The quality of a modular building is a lot better than an on-site build, because its elements are created by the right craftsmen doing the right jobs in ideal conditions,” Harris says. “That’s why bathroom modules are so popular. Talk to any hotelier and they’ll tell you most guest complaints are about bathrooms – whether they’re functioning and clean.”

The regimented checks that modular bathrooms go through before getting anywhere near the building site means that there are fewer defects at completion of the build and ongoing maintenance issues once the room in operation. Elements of the guest experience such as the soundproofing between rooms and on windows are also apt to be better, Harris says.
