Retrofitting A Whirlpool Tub, continuedProviding access. With a
bow to Murphy's law, every whirlpool tub requires an access
panel to permit work on the pump, wiring, and hoses. Removing a
pump is usually a simple matter. Most pumps are secured by just
two plumbing unions and four bolts. In most whirlpool models,
the pump is located at the foot of the tub, opposite the
waste-and-overflow, so that's usually the best place for the
access panel (Figure 6). If it can't be located there —
because of back-to-back bathrooms or a chimney at the foot of
the tub, for example — the next best place is in the
front skirt.

whirlpool tubs. As long as the location is not blocked
by a chimney or other obstruction, it's the best place
for the access panel. |
If the tub comes with a removable skirt, access is no
problem (Figure 7). If a site-built skirt requires an access
panel, I include a square opening in the framing, cut a panel
out of backerboard, and install it with screws for future easy
removal. Since a visible panel in the skirt detracts from a
bathroom's aesthetics, I usually tile right over the access
panel and screws, using mastic instead of a thinset mortar
mix.

Royale (top) and the Nostalgia (bottom) from Crane
Plumbing, come with a removable skirt that provides
access to the pump and hoses. |
I always make a sketch of the access panel location,
including measurements, and give a copy to the customer and
keep one for myself. If the access panel ever needs to be
removed, some tiles will probably get broken, so I arrange with
the customer to store some extra tiles, clearly marked, in a
safe place. In any case, access panels are rarely used; I've
only had to pull one pump in the last ten years.
