How to handle floor height differences between rooms
Dealing with significant height gaps between rooms forces a choice between tearing out existing tile to match levels or bridging the gap with transition strips and leveling compounds. However, standard reducers only support small height differences up to about 15mm, leaving steep transitions or massive 1.5-inch drops in tight doorways without a standard premade fix.
