Barbara Cullinane has spent 28 years in the remodeling industry. After decades of broad remodeling work across Florida, she made a deliberate choice — stop doing everything and get really good at one thing. That is bathrooms. Specifically tubs and showers. That focus means every project gets the full weight of her experience behind it. No generalists, no learning on the job. Just a contractor who has done this long enough to get it right every time.
Most homeowners assume a quality bathroom renovation means an expensive one. Barbara built Discount Tub and Shower around the idea that it does not have to work that way. By focusing exclusively on tubs and showers and using Sentrel Bath Systems — a proven, mold-resistant product — she keeps costs honest without cutting corners on materials or installation. The goal has always been simple: give homeowners across the Treasure Coast a bathroom they love, at a price that makes sense.
Our Team
Owner & Bathroom Renovation Specialist
Barbara handles every project personally, from the first phone call to the final walkthrough. With 28 years of remodeling experience behind her, she brings a level of hands-on knowledge that most contractors in the area cannot match. Her approach is straightforward — treat every customer's home like her own, deliver what she promises, and never leave a job she is not proud of.

Your shower should be clean, modern, and easy to maintain. We replace outdated tile, worn surrounds, and aging fixtures with Sentrel Bath Systems — a non-porous material that resists mold and mildew from day one. Every shower remodel is custom-designed to fit your space and your style. The result is a bathroom that looks better and stays cleaner, longer.

If you have a bathtub you rarely use, converting it to a shower is one of the smartest updates you can make. We remove the old tub completely and install a custom shower in its place — no mess, no lengthy construction timeline. The process is clean and efficient, and we handle everything from demo to final installation. You get more usable space and a bathroom that fits how you actually live

A walk-in tub is a practical solution for anyone who wants safer, more comfortable bathing. We install walk-in tubs that combine accessibility with durability — built to last and easy to clean. These are a popular choice for seniors or anyone dealing with mobility challenges. You get the comfort of a real bath without the risk of stepping over a high tub wall.

Sometimes a bathroom needs more than one update. We handle full bathroom remodels from start to finish — replacing surfaces, fixtures, and layouts to give you a space that functions well and looks great. Every detail is planned and executed with care, on a timeline that respects your home and your schedule. No subcontractors, no surprises.

An old bathtub can drag down the entire look of a bathroom. We replace worn, stained, or cracked tubs with quality materials built to hold up over time. Most bathtub replacements are completed in a single day. You get a fresh, clean look without a drawn-out renovation.

Mold in a bathroom is more than a cosmetic issue. Our Sentrel Bath Systems installations use non-porous acrylic wall panels that do not absorb moisture — which means mold and mildew have nowhere to grow. This is one of the main reasons homeowners choose us over traditional tile contractors. A cleaner bathroom with far less maintenance over time.

Bathrooms should be safe for everyone in the home. We modify existing bathrooms to improve safety and accessibility — including low-threshold showers and walk-in tub options. These changes make a real difference for seniors, people recovering from injury, or anyone with mobility concerns. Every modification is done with attention to how the space will actually be used day to day.

Not every bathroom is the same, and your shower should not be either. We work with you to design a shower that fits your space, your style, and your budget — from shelf placement to door style to wall panel color. Then we install it right: clean, fast, and built to last.

Getting in and out of a shower or tub should not feel like a risk. We modify existing bathrooms to make them safer and more accessible — adding low-threshold shower entries, walk-in tub options, and other targeted changes that reduce the chance of slips and falls. Every upgrade is built around Sentrel Bath Systems, so the surfaces stay clean and low-maintenance long after the job is done. The result is a bathroom that works better for the people who use it every day.

Sentrel Bath Systems is a non-porous acrylic wall panel system designed specifically for bathrooms. Unlike tile, it has no grout lines — which means no places for moisture, mold, or mildew to settle in over time. It cleans easily, holds its appearance for years, and performs far better in Florida's humid conditions. We use it on every installation because it simply outlasts traditional options.
Converting an unused bathtub into a walk-in shower is one of the most practical bathroom upgrades a homeowner can make. Many buyers today prefer showers over tubs, especially in master bathrooms. Beyond resale value, the bigger benefit is daily usability — most homeowners who make the switch say they wish they had done it sooner. We handle the full conversion from demo to final installation.

Mold in a shower is almost always a materials problem. Traditional tile grout absorbs moisture, and in Florida's humidity, mold grows back no matter how often you clean it. The permanent fix is replacing those surfaces with a non-porous material like Sentrel Bath Systems, which gives mold nowhere to take hold. We handle that replacement from start to finish, and most jobs are completed in a day or two.
