These kind of showers are awesome.
They got those in Ramada Encore hotel in Bangkok.
I highly recommend that hotel; reasonable price, good standard, good location (between Asok and Nana station), free wifi (though insecure), decent tv channels.
But whatever you do don’t order the lamb chop at 600 baht, it’s very small. Also you might want to bring some water into the hotel as you only get two small bottles per room day for free.
