When Jason and I went to Costa Rica for my sister and brother-in-law’s wedding a couple years ago, we stayed at a beauty house in Manuel Antonio. Somehow Jason and I ended up with the bedroom with the biggest bathroom. It had a huge walk in shower with two shower heads. We were sold. We decided when we renovated our master bathroom, it absolutely had to have duel shower heads. We made this shower 4’x5′, probably less than half of the size of the one in Costa Rice, but still plenty big. We did all the tile work by hand and it took a ridiculously long time. A true labor of love for us and our house.
