Shower renovations

A Shower That Looks Right and Stays Dry

Shower renovations for homes across Wasaga Beach, Collingwood, and Clearview start with doing the hidden work properly. Mighton Construction rebuilds the shower from the substrate out: framed and sloped correctly, sealed with a continuous waterproof membrane, then finished with tile, glass, and fixtures you chose.

Many bathrooms here were built to cottage standards, with tub-shower combinations, fibreglass stalls, and tile laid over unprotected board. We replace those with custom tile showers, walk-in showers, and curbless designs, handled as part of a full bathroom renovation so the floor, drain, walls, and ventilation all work together.

What a shower renovation includes

We start by looking at your current layout and what you want to change: the size and position of the shower, the entry, the glass, and the finishes. From there we settle the plumbing and structure, plan the waterproofing, and agree a detailed scope and material list before demolition begins. Our bathroom renovation process then keeps the time without a working shower as short as we can.

Want to understand the build first? Our guide on how to build a custom shower walks through each stage. If the shower is part of a larger plan, we also renovate primary ensuites, accessible bathrooms, and basement bathrooms.

Shower options

Walk-In, Curbless, or Tub-to-Shower

The right shower depends on the room, the plumbing, and how you live. We help you choose, then build it properly.

  • Custom tile showers sized and laid out to your bathroom, with niches, benches, and tile patterns
  • Walk-in showers with frameless glass and a low or flush entry
  • Curbless showers with a sloped floor that drains without a step, a good fit for accessible bathrooms
  • Tub-to-shower conversions when they are part of a full bathroom renovation

Curbless showers

A Flush Entry Starts in the Floor

A curbless shower looks simple because the hard work is hidden. The floor has to slope to the drain across the whole shower, which often means changes to the subfloor and drain position, so we plan it at the start of the project.

  • Subfloor and drain position assessed before the design is fixed
  • A long linear drain or a centre drain, chosen for the room
  • Useful for barrier-free bathrooms, though a curbless shower alone does not make a bathroom fully accessible

Replacing a tub

From Tub to Walk-In Shower

Swapping a tub for a walk-in shower changes the plumbing, the floor, and the walls around it. We handle it as part of a full bathroom renovation, and it is a good moment to reconsider the whole layout rather than only the tub footprint.

What is behind the tile

Waterproofing Is the Whole Job

Most shower failures are waterproofing failures, and they stay hidden until the damage is done. We build the shower from the substrate out so it is sealed before any tile goes on.

  • A continuous waterproof membrane system, Schluter-KERDI or equivalent, installed across the whole enclosure
  • Correct slope to the drain so water leaves the floor instead of sitting on it
  • Framing and subfloor protected from moisture, the most common cause of bathroom failures
  • Ventilation sized to the room so humidity does not undo good work

Our Shower Renovation Process

01

Consultation & Measurement

We visit your home, measure the space, discuss your goals, and review your budget. We identify any plumbing, electrical, or structural considerations that will affect the design.

02

Design & Material Selection

We work with you to select tile, fixtures, vanities, shower systems, and lighting. We provide guidance on what performs well and what delivers the best value.

03

Pre-Construction

Materials are ordered, trades are scheduled, and any required permits are secured. We plan the construction sequence to minimise the time you are without a functioning bathroom.

04

Demolition & Rough-In

The existing bathroom is stripped, plumbing and electrical are relocated as needed, and any structural or subfloor issues are addressed.

05

Waterproofing, Tile & Finishing

Waterproof membranes are applied, tile is set, fixtures are installed, and all finishing details — paint, trim, accessories — are completed to a high standard.

Common questions

Frequently Asked Questions

Do you do shower-only renovations?
We take on shower renovations as part of a full bathroom renovation, not as quick fixture swaps. If you are replacing the shower, the floor, drain, waterproofing, and surrounding walls are all in play, and doing them together is how we make the result last. Tell us about your project and we will confirm the right scope.
How much does a shower renovation cost?
A full renovation of a standard three-piece bathroom, including a new shower, starts around $20,000. Primary ensuites with custom tile showers, freestanding tubs, and premium fixtures typically run $35,000 to $75,000+. We provide a detailed budget before work begins.
How long does a shower renovation take?
Most bathrooms take about 10 working days on site. We order everything first and do not start demolition until the materials are on hand. Large showers with extensive custom tile or layout changes can take longer, and we confirm your schedule in writing before work begins.
Can you convert a tub to a walk-in shower?
Yes, as part of a bathroom renovation. A walk-in shower can replace the tub, and we assess the plumbing, the floor structure, and the waterproofing before settling the design. Often it is worth reconsidering the whole room layout at the same time.
Can you build a curbless shower?
Yes. A curbless shower needs a sloped floor and, in many cases, changes to the subfloor and drain. We plan this at the start. It suits barrier-free bathrooms, though a curbless shower alone does not make a bathroom fully accessible.
How do you waterproof a shower?
We use Schluter-KERDI or an equivalent membrane system to create a fully waterproofed enclosure before any tile is installed. This keeps moisture away from the framing and subfloor, which is the most common cause of bathroom failures.
Are heated floors worth it?
In this climate, they are the upgrade clients thank us for most. Electric in-floor heat under tile costs relatively little during a renovation, takes the chill off winter mornings, and helps the floor dry faster. Retrofitting later costs far more — if you are tempted, do it now.
What happens if you find mould or rot behind the walls?
We document it, price the correction transparently, and fix the cause — not just the symptom. Because our budgets are open-book, hidden-condition work is priced at actual cost with your approval before it proceeds. We never tile over a problem.
Can we supply our own fixtures and tile?
Yes, with guidance. We are happy to install owner-supplied fixtures and tile, and we will flag quality or compatibility issues before you buy — some products look great online but fight the installer and fail early. Anything we supply is priced open-book.
How many bathrooms can you renovate at once?
If your home has more than one bathroom, we typically renovate them in sequence or stagger the work so one is always functional. Doing two or three in a single project saves mobilization cost and gets all the disruption over with at once.
How does your open-book, cost-plus pricing work?
You pay the actual cost of materials, labour, and subcontractors, plus a clearly defined management fee — and you see every invoice along the way. There are no hidden markups or padded allowances. It keeps our interests aligned with yours: we have no incentive to cut corners, because we do not profit from the difference.

Full answer: How does open-book, cost-plus pricing work?

Do you handle building permits and inspections?
Yes. Depending on the project scope, we coordinate or fully manage permits with the municipality, arrange required inspections, and handle conservation authority applications where properties in South Georgian Bay need them. Every project we build is permitted and inspected.
Can you work from plans we already have?
Absolutely. We regularly price and build from completed architectural drawings. If you are earlier in the process, we can also coordinate design and pre-construction planning with architects, designers, and engineers we trust.
Are you licensed and insured?
Yes. Mighton Construction Limited carries $5 million in aggregate liability coverage and maintains WSIB coverage for applicable work, with clearance information available on request. All work is built to Ontario Building Code and inspected by the local building department.
What happens after I submit the contact form?
We aim to respond to serious project enquiries within 1–2 business days. The first step is a free phone conversation about your goals, timing, location, and rough budget. If the project is a good fit, we arrange a site visit and provide early guidance and a ballpark estimate.
How far in advance should we get in touch?
Earlier than you think. We intentionally take on a limited number of projects each year so Jeff and Adam stay personally involved in every one — which means our calendar fills ahead of the season. Talking early also gives design, permits, and material lead times the room they need.
