water is seeping out from under tub and soaking wood floor
Maybe, but probably not. Most likely there is a leak either in the pipes at the valve or shower head or the caulking or grout (if any) has failed. There is sometimes an access hatch on the valve wall (opposite wall-side). This will give you a view of the plumbing. If not look closely on the shower wall for any gaps or cracks that need sealant or caulking.
