Hi with ur budget RM50/mth can consider LG WD516 (got hot, cold and ambient water) ya

Ori price is RM60/mth, but current promo is to clear stock for white color, so only RM50/mth

Or if u like more function or the design, LG WD518 is our latest model, but its RM60/mth

Ur site I think can install using an adaptor (install vertically instead of horizontally as show in pic)

Also, LG provides every year 1 time free relocation, so no worry if u keep moving every year
