A made-to-size mirror is usually ordered for one of three reasons: the wall is not a size any stock mirror matches, a socket or light falls inside the mirror footprint, or a previous mirror left fixing holes that the new one has to cover. All three are solvable, and all three are solved by measurement rather than by choice of frame.
What You Can and Cannot Customise
Width and height are the easiest variables, followed by edge finish: flat polished, beveled, or a safety edge. Shape is also achievable - arched, rounded corners, a cut corner for a sloped ceiling - though more complex outlines add both cutting time and risk. Cut-outs for sockets, switches or a light fixing are standard fabrications.
What cannot be changed is the material after manufacture in one respect: if the mirror is safety-backed or mounted with a specific backing, the fabrication is set at order stage. The same principle that applies to tempered glass applies here - the piece is made to the drawing, so the drawing has to be right.
Measuring an Irregular Wall or Alcove
Measure the width at the top, middle and bottom of the intended position, and the height at both ends, then use the smallest figures. Where the wall is out of plumb, a rectangular mirror leaves a visible taper; the choices are to size to the narrowest point, to shim the mirror off the wall, or to accept a small gap at one edge.
Measure the fixing positions as well, particularly if an existing mirror is being replaced, because new fixings that fall into old holes are a gift. Record the height from the floor to the intended bottom edge and the position from a fixed reference such as a corner or the basin centre.
Cut-Outs for Sockets, Lights and Switches
Cut-outs are positioned from a defined reference - usually the bottom left corner - and given as centre distances to each hole. Confirm the diameter or the shape required, and whether the fixing or socket needs clearance behind the mirror, since some fittings are deeper than the glass and backing together.
Where a socket sits behind the mirror, access becomes a maintenance question: a cut-out that exposes the socket face is one thing, while a mirror mounted over it permanently is another. If the fitting has to remain usable, design the mirror around it rather than over it.
Lead Time From Measure to Delivery
Made-to-size mirrors are fabricated to order, so lead time starts at the confirmed drawing rather than at the enquiry. Complex shapes and beveled edges take longer than rectangular panels with a flat polish, and a bevel adds a second operation after cutting.
The schedule consideration is that the mirror is usually installed near the end of a project, after tiling and painting. Ordering early enough that the mirror arrives after the wall is finished, but before the final cleanup, is the practical balance.
Custom Shapes and Edge Profiles
Arched tops, rounded corners and cut-outs for a sloped ceiling are common custom shapes, and each changes how the edge is finished: a curve needs a polished edge that follows the profile, and a bevel is more difficult on a curve than on a straight edge. For most custom shapes a flat polished edge is the more reliable specification.
Where the mirror is framed instead, the frame carries the shape and the glass is cut to suit, which is often simpler for unusual outlines. Frame finishes can be matched to the room's hardware in Matte Black, Chrome, Brushed Nickel or Brushed Gold.
Installing a Made-to-Size Mirror
A large mirror is a two-person lift with suction cups, and the fixing method is decided by the wall: clips that reach framing or rated anchors, a channel, or mirror mastic with clips for stability. Blocking behind the wall is worth adding wherever the wall is open, because it converts a future replacement from a problem into a task.
Level from a marked line rather than from the floor, and dry-fit the mirror or a template before fixing. General fixing requirements follow the adopted building code published at iccsafe.org; where the mirror serves an accessible lavatory, the position and mounting provisions are described by the US Access Board; and glass used in a bathroom is covered by the architectural glazing provisions of 16 CFR Part 1201. Component test methods are published by ASTM International, and where an old mirror has been hiding moisture damage, the EPA moisture guidance explains what to check before the new panel goes up.
Comparing Custom Cost With Stock Sizes
A custom mirror costs more than a stock size because it is cut, edged and drilled to a drawing, and because a mistake is not recoverable. The comparison changes when a stock size would need filler, when a socket has to be worked around, or when the fixings from a previous mirror would be left exposed.
Compare on the finished result rather than on the panel price: a stock mirror plus a frame to cover a gap is not necessarily cheaper than a made-to-size panel, and a mirror that has to be replaced because it does not fit costs more than either.

FAQ
How much does a custom bathroom mirror cost?
Price is driven by the area of glass, the thickness, the edge finish, the complexity of the outline and the number of cut-outs, plus delivery. A rectangular panel with a flat polished edge is the least expensive custom shape; beveled edges and curved profiles add a second operation and more risk.
Where can I find a custom-sized bathroom mirror?
Order from a supplier that fabricates to a drawing and confirms the dimensions with you before production. Send the width at three heights, the height at both ends, the fixing positions, and the cut-out positions measured from a defined corner so there is no ambiguity.
Can a mirror be cut to fit around a socket?
Yes. Cut-outs for sockets, switches and light fittings are standard fabrication, positioned by centre distances from a defined corner. Consider whether the fitting has to remain accessible: a mirror mounted permanently over a socket may meet the drawing but not the way the room is used.
What kind of bathroom mirrors are in style right now?
Frameless panels with polished or beveled edges, slim metal frames in matte black and brushed finishes, backlit LED designs, and shaped mirrors over single basins. The common thread is proportion with the vanity and the lighting rather than a decorative style.
Send the wall width at three heights, the height at both ends and any cut-out positions, and we will confirm the mirror size, edge finish and mounting method.
