Bathroom. The goal here is to install washer and dryer under countertop. To solve this task, countertop was elevated a little bit higher then average standard. Since space under countertop is busy with washer and dryer, the biggest challenge was to install sink boul. If simply put sink on the countertop, then it goes to high, because countertop already was elevated to allow washer and dryer remain under it. I did not consider shallow sinks, because they are not convenient at all. Also it was not possible to install under mount sink, because there are washer and dryer. Eventually i found sink that is half in, and half above countertop, and increase a little bit of countertop thickness. As a result this solution allow to have both washer and dryer, comfortable pretty deep sink and huge countertop to keep bathroom stuff on it. . Another important element in the bathroom is tankless electrical water heater, Its New York, so water tank for all units installed on the roof. Building is old and big, so sometimes building tank is lack of hot water. To set tankless electrical water heater two extra valves were installed on hot and cold pipes. In case there is no hot water, i close main hot water valve, open cold one that right before heater, to let cold water go inside heater, and open another valve, that deliver hot water into the system after heater. This task also required installation of new electrical cable, because tankless heaters requires a lot of power. . The last thing is pretty big, 48”x30”, embedded wall cabinet, with three big parts and mirror doors. To support this cabinet, extra wood frame structure was built inside wall, that was designed thicker to allow build-in cabinet set inside. .
