Nope... I didnt spray.. I placed a tempered piano pink glass on top of the green tile.. my id give it for free... Homewarming gift from the company... hahaha... Anyway, I would not recommend a gas heater... the reaction is **** slow.. it took close to 5mins to heat up... dont really know why.. i prefer conventional heater at respective bathroom.. fast and good... if u realise there are opening piping at the common bathroom reflecting a cold and hot pipe.. form the service yard, they punch a hole thru the wall... and run extra piping on the common bathroom thru the cover up netted ceiling... quite hidden.... Anyway, my MBR shower had a low flowrate.. not powerful enough...how to increase the flowrate.. they told me that there is a saving water component hidden in the shower head... i try to opened it.. i dont see any...installation is $128 including the heater... add inside our next pub bill
