Exquisite 6-Gothic Gothic Athena. Diameter 6m, Oak wood. All parameters are optional according to wishes. Material (recommended oak), cross section, height, diameter, style. The possibility of lighting with optical fibers, which can not be burned, does not matter any moisture.
Design of circular shower. Several variants of the design are considered. Wood, artificial sandstone, hypothetically seems to me to be a variant with a styrene core and a surface called a stone carpet. In the groove, an optical fiber with side radiation is embedded in the epoxy resin, so there is no risk of burning, nor is there any contact with water.
