If you’re comparing One-Day Bath installations and tub-to-shower conversions and want to know what they actually cost before you call anyone, this page gives you real numbers — broken down by scope and what drives the price in either direction.

One-Day Bath installations and tub-to-shower conversions in Cecil County MD, Harford County MD, New Castle County DE, and Chester County PA typically range from $8,000 to $12,000+ depending on the scope of work, materials selected, and whether plumbing changes are involved.

  • Basic One-Day Bath (tub surround replacement, new fixtures, same-day install): $8,000–$9,000
  • Tub-to-shower conversion (wall panels, new shower base, new fixtures): $9,000–$12,000
  • Tub-to-shower with frameless glass enclosure and upgraded finishes: $12,000–$16,000+

The most significant cost variable in this type of project is the wall system. High-quality acrylic or composite wall panels are the basis for a same-day installation and come in at a lower cost than custom tile work. If you want custom tile in the shower, the project moves from a One-Day Bath to a full shower renovation — which takes longer and costs more. Both are options we offer; we’ll help you choose during your estimate.

Adding a frameless glass door or enclosure is one of the most popular upgrades for tub-to-shower conversions — it makes the finished shower look significantly more custom and high-end. Glass adds $1,500–$3,000+ to the project depending on configuration.

Tub-to-shower conversions sometimes require plumbing modifications — especially if the existing tub valve and drain need to be relocated or replaced. This adds cost but is handled in-house by our team as part of the project.

Larger or non-standard tub footprints require more material and more labor, which pushes the cost higher. Most standard 60-inch tub spaces convert cleanly and efficiently.

Grab bars, built-in shelving niches, handheld showerheads, and upgraded fixtures can all be added during installation. Each adds modest cost but can significantly improve the usability and appearance of the finished shower.

A standard One-Day Bath — replacing your existing tub surround with a new wall system and fixtures while keeping the tub — is typically the lower-cost option. The existing tub base stays in place, which reduces demo and plumbing work.

A tub-to-shower conversion removes the tub entirely, installs a new shower base, wall system, and fixtures — and often adds a glass enclosure. The additional scope (tub removal, new drain, possible plumbing adjustment) puts it at a higher price point than a basic surround replacement.

Both options are completed in one day using wall panels. Custom tile elevates the look further but takes longer and costs more.

  • Removal and disposal of existing tub surround or tub (for conversions)
  • New wall panel system — custom-fitted to your space
  • New shower base or tub base (if replacing)
  • New showerhead, faucet, and hardware
  • Optional: glass door or enclosure, grab bars, built-in shelving, handheld wand
  • Waterproofing throughout
  • Same-day completion and cleanup

How much does a One-Day Bath cost in Maryland?

In Maryland — including Cecil and Harford County — One-Day Bath installations typically range from $8,000 to $9,000 for a standard tub surround replacement with new fixtures. Tub-to-shower conversions run $9,000–$12,000+ depending on materials and scope.

How much does a tub-to-shower conversion cost?

Tub-to-shower conversions with Modify Remodeling typically range from $8,000 to $12,000+ in our service area — Cecil County MD, Harford County MD, New Castle County DE, and southern Chester County PA. The range reflects differences in wall material, glass enclosure choice, and plumbing requirements.

Is a One-Day Bath actually completed in one day?

Yes. One-Day Bath installations using wall panel systems are completed same-day in most standard tub and shower configurations. Our crew arrives in the morning and completes the full installation before leaving. Custom tile showers are not same-day — those are a different scope and timeline.

Why does a tub-to-shower conversion cost more than just replacing the surround?

A tub-to-shower conversion involves removing the existing tub (not just the surround), installing a new shower base, and often adjusting the drain and plumbing to accommodate a shower-only setup. The additional demo, materials, and plumbing work push the cost higher than a basic surround replacement.

Can I add a glass door during a tub-to-shower conversion?

Yes — and most homeowners do. A frameless glass door or enclosure is a popular add-on that makes the finished shower look significantly more polished. It adds $1,500–$3,000+ depending on the configuration and is installed as part of the same project.

How do I know if I need a One-Day Bath or a full bathroom remodel?

If your bathroom is otherwise in decent shape — the vanity, flooring, lighting, and layout are fine — but the tub or shower area is the problem, a One-Day Bath or tub-to-shower conversion is almost certainly the right fit. If the whole room needs work, a full remodel makes more sense. We’ll give you an honest recommendation during your free estimate.
