What Happens When a 1970s Alcove Tub Finally Gives Out in South Tampa?
The situations described here are composites drawn from the types of jobs and decisions we encounter regularly. Names and specific figures are illustrative.
The call came in the second week of June. The bathtub in the hallway bath of a 1970s ranch off Bay-to-Bay had finally stopped draining in any reasonable time. She wanted to talk about bathtub replacement in Tampa, FL before she made decisions about tile, vanity, or the rest of the bathroom she had been putting off for ten years.
Where the call usually starts
She had assumed she wanted a like-for-like swap. New tub, same place, same plumbing, fresh tile surround. The first thing we did was pull back the access panel in the linen closet. Behind that panel was original galvanized supply, a brass drain shoe, and a cast iron P-trap wrapped in plumber’s putty by someone who clearly meant well in 1978. The drain rough-in sat closer to 12 inches from the back wall, not the modern 14. None of that was visible from inside the bathroom.
Cast iron, steel, or acrylic
The existing tub was cast iron — older South Tampa homes built between the late 60s and early 80s often have them. Holds heat, dampens sound, lasts longer than the people who installed it. The downside is weight: 320 pounds empty. Replacing it means joist span discussion.
Enameled steel: lighter, porcelain finish that resists scratching but chips if a heavy bottle drops. Acrylic: lightest, warmest, most forgiving on rough-in variation, but scratches under abrasive cleaners and dulls with daily use.
The tub itself was the smallest line item. Whether she chose a $400 steel tub or a $1,400 cast iron one, the demolition, drain work, wall repair, new valve, and surround were going to look similar.
The drain rough-in surprise
Once we opened the wall, the drain became the project. The original 1.5-inch galvanized branch had narrowed to maybe three-quarters of useful diameter from forty-eight years of scale. The trap was on the wrong side for a modern tub’s drain shoe.
Cutting slab in a South Tampa home from that era is a decision in itself. We proposed replacing the branch with PVC back to the nearest accessible drain, using an offset shoe to bring the new tub’s drain to the existing trap. Four working days instead of seven.
When converting to a walk-in shower is the better answer
Does the house need this tub at all? She had two bathrooms. The primary already had a walk-in shower. The hallway bath was used by her teenage son and guests once or twice a year. She had not taken a bath in either tub in roughly four years.
Does removing a tub hurt resale? In Tampa, as long as the home keeps at least one tub somewhere, buyers do not penalize a walk-in shower in the secondary bathroom. If the primary already has a shower-only setup and the secondary bath has the only tub, converting that one hurts resale. Her case was the inverse.
Our notes on which renovations add the most value in Tampa homes cover the broader pattern.
What she chose
Mid-grade steel tub, white, slip-resistant bottom. She kept the alcove configuration but we set up the framing and drain so a future tub-to-shower conversion would be straightforward. That decision had to be made before we closed the wall.
Demo took most of one morning. Drain and supply work took the rest of day one and the first half of day two. The new tub went in that afternoon, set in mortar to deaden flex and reduce the cold-floor effect. Days three and four were cement board, tile surround, grout, caulk, trim.
Total cost landed where she budgeted. The tub itself was under fifteen percent of line items. Anyone quoting a flat one-day price without seeing behind the wall is quoting a hope.
What the reader can take from this
If the house is a 1970s ranch in South Tampa or Town ‘N Country, expect the drain rough-in not to match modern tubs. Plan on an access panel and an honest look at supply lines before committing to a material. The choice between materials matters less than how often the tub gets used and whether the household actually wants one there.
Whatever direction the project takes, the work behind the wall determines whether the installation lasts twenty years or starts leaking in three. For homeowners weighing a bathtub replacement in Tampa, FL, open the access panel and see what is actually there. A look at past projects shows how often the same pattern repeats.
