Plan the shower enclosure early, but confirm its final dimensions from the finished opening before releasing the glass order. For a tiled shower, that generally means completing the surfaces the glass will meet, rather than measuring between bare studs and hoping the finished size works out.
There are two decisions to coordinate: what enclosure the bathroom will accommodate, and the exact dimensions needed to make or select it. Separating those decisions helps avoid ordering too soon without leaving important support and layout choices until after tiling.
Choose the approach before the walls are closed
A stock shower door and a made-to-measure enclosure need different planning.
- Stock enclosure: identify the exact model early. Its permitted finished-opening range, height, threshold requirements and hardware determine whether it will suit the proposed shower. A product advertised for a nominal shower size is not a substitute for checking its installation specifications.
- Custom glass: discuss the arrangement and hardware early, then have the supplier measure the completed opening for fabrication. Custom sizing can accommodate a particular design, but it does not mean every uneven wall or awkward doorway is acceptable.
DreamLine’s measuring guidance distinguishes a shower-base measurement between studs from a shower-door measurement between finished walls. Backing, tile and other finishes change the available space. Its guidance also calls for measurements at several heights and checking whether walls are plumb.
If a supplier proposes measuring earlier, ask what remains unfinished and how the final dimensions will be verified before the order is released. Make responsibility for that verification explicit.
Resolve support, door movement and fixing details first
A wall-mounted hinge may require reinforcement behind the finish. For example, the DreamLine Unidoor Style A manual specifies reinforcement at its hinge locations. That requirement is product-specific, not a universal framing detail.
Give the selected enclosure instructions to the contractor before wall construction is finalized. Agree on the hardware locations, backing and any support bars while changes are still straightforward.
Also review the door in the actual bathroom. Where will it swing? Will the handle meet the vanity or towel rail? For a sliding door, how much entrance space remains when it is open? These checks should consider the person entering, reaching the controls and cleaning the enclosure, not only how the glass looks in a product photo.
Fastening must suit both the enclosure and the shower assembly. HYDRO-BLOK’s guidance for mounting a hinge on its curb, for instance, describes a system-specific detail. It is not permission to drill through any shower curb. Have the installer resolve compatible fixing and sealing details before work proceeds.
What should be ready for the final measurement?
Ask the glass supplier for its readiness checklist. The surfaces defining the enclosure should be established: finished walls, threshold or curb, and any return or half-wall that the glass meets. A planned tile change or new cap on a half-wall can change the geometry.
Basco’s measuring guide records more than a single width and height. Its checks include wall alignment, threshold conditions, angles, returns and relevant showerhead positions. This is why a quick homeowner measurement is useful for an initial discussion but should not automatically become the fabrication instruction.
Before the appointment, tell the supplier about any finish work still outstanding. Decide who takes the final measurements, who approves the design and who authorizes ordering. Avoid passing an approximate drawing between several people without a clear sign-off.
Allow for the work after measuring
Final measurement is a milestone, not necessarily the last visit. Fabricator Dulles Glass explains that completed tile work precedes its measurement, which informs glass sizes and hardware selection; design approval comes before fabrication or procurement.
For your Niagara renovation, ask the chosen supplier which event starts its quoted lead time. Does it begin at measurement, design approval or order release? Confirm who will coordinate delivery and installation with the rest of the bathroom work. Do not assume a quoted fabrication period includes all of those steps.
Installation day is not necessarily first-use day. Follow the applicable product and sealant instructions for curing and water exposure. The Unidoor manual includes a waiting period and silicone guidance, not a universal waiting time for every shower.
Questions to settle before ordering
- What exact model or approved custom arrangement are we ordering?
- Are the final wall and threshold finishes complete?
- Have support, fixing locations and waterproofing details been coordinated?
- Who is responsible for measuring and approving the final dimensions?
- What starts the lead time, and what could change it?
- Who confirms when the shower is ready for use?
Shower-glass planning FAQs
Can the glass be trimmed if it arrives too large?
Do not rely on that. The DreamLine manual warns that tempered glass cannot be cut after it has been tempered. Accurate sizing and approval matter before fabrication.
Should I wait until tiling is finished to choose the door?
No. Choose the enclosure approach early enough to coordinate the opening, support and hardware. Final sizing is a later check against the completed surfaces.
Does a tub-to-shower conversion follow the same sequence?
The same distinction between early planning and final sizing applies. The base, wall finishes and room layout also need coordination; our tub-to-shower conversion guide covers the wider scope.
