Hello all: Newbie here!

Problem: New Jacuzzi tub going in in a U shaped enclosure (in the master bath remodel). Drain is at the short end of the U and will be about 5 ft. away from the entry end for the tub.

Have looked at the cable drains at Lowes and on line. What I want is a cable drain with about a 6 ft. cable so it can be placed at the accessible end of the tub. Otherwise, we will have to climb into the tub to open or close the drain.

Question: With the multitude of cable drains available at all sorts of prices, has anyone added a longer cable to an existing product...Or, is there a "long cable" product available?

Any Info greatly appreciated
