Using this Danze by Gerber Square Roman Tub Handshower Rough - In is easy. First, make sure you have the Square Roman Tub Personal Spray, as it's required and sold separately. Connect the rough - in using the 1/2'-14NPSM connection. Attach the included durable 72' all - metal interlock shower hose with brass conicals to the appropriate parts. Hang the hose on the hose holder and set up the diverter. When it comes to maintenance, regularly check the connections for any signs of leakage. If you notice any, tighten the connections gently. Keep the all - metal hose clean by wiping it with a soft cloth. Avoid using harsh chemicals on the hose or the other components as this may damage them. Store any optional parts in a dry place when not in use.
