The bathroom is real or for decoration? … (yes I am asked a lot …)
The baths and Wooden sink are made of extremely durable wood varieties. In addition to the process of finishing the bath I use materials that seal the wood inside and out and prevent water contact with the wood. This enables their durability over the years.
The bath and sinks are cleaned with a regular sponge and soap, do not use pungent acids or bleach.
