There's no published report that breaks shower door search volume by category into clean monthly numbers for 2026 — no major keyword tool splits query volume between neo-angle, pivot, barn-door, and framed-versus-frameless shower doors. The closest real signal sits inside the catalog itself: how Century Shower Door's 55 published guides are distributed across categories, which categories carry the deepest coverage, and which ones are nearly empty.

Why this matters

Search tools lump most shower door queries into one broad bucket and rarely split results by sub-category, so a founder asking "which shower door category gets the most search volume" usually gets no real answer in 2026. Century Shower Door's own guide library is the next best signal: it shows where buyer questions cluster heavily enough to justify a dedicated page, and where the catalog has gone quiet.

That split matters for two decisions: where to pitch the next round of content, and which category is already crowded enough that a new guide competes against Century Shower Door's own pages instead of a competitor's. Century Shower Door adds category guides throughout the year, so a thin category below is a planning gap, not proof of low demand.

Shower door category coverage: the 2026 benchmark

The short answer: manufacturer and brand comparisons are the most heavily covered shower door category on showerdoor.com, with 15 of 55 guides, 27% of the library. Cost and regional topics are the thinnest, at 1 guide each, 2% of the library. Everything else — door styles, installation workflows, maintenance, trade-professional guides — lands between 4 and 8 guides per category.

Here's the full count, pulled directly from the published guide library as of 2026:

Manufacturer and brand comparisons lead at 15 guides, nearly double the next closest group, because head-to-head pages like the shower door manufacturers compared guide compete directly against alternative-brand searches. Cost and regional guides trail at 1 guide each, which means a shower door cost page or a location-specific page faces almost no internal competition inside Century Shower Door's own catalog right now.

These counts come from the live published guide library on showerdoor.com, categorized by topic for this 2026 review. One limitation worth naming: guide count measures content supply, not confirmed search demand — a category can carry real buyer intent with only one published guide, and a 15-guide category can include pages competing for very different terms from one another.

A closer look: door styles and maintenance

Door style and type comparisons — neo-angle, sliding, pivot, barn-door, framed-versus-frameless — tie with installation/technical guides and maintenance/cleaning guides at 7 each, 13% of the library apiece. That's not a coincidence. A homeowner shopping a shower door category almost always asks a style question first, then a fit/installation question, then a maintenance question once the door is in. Covering all three at the same depth keeps the buying journey inside Century Shower Door's own catalog instead of sending that reader to a manufacturer forum or a competitor's blog.

Maintenance and cleaning guides cover sealant and caulk comparisons, water-stain removers, low-maintenance coatings, squeegees, and sweeps and seals — all topics tied to a door that's already installed, not one still being chosen. That's a different reader intent than the style-comparison group, even though both sit at the same 7-guide depth in 2026.

How to use these benchmarks

• Treat the 15-guide manufacturer-comparison category as saturated relative to the rest of the catalog — audit conversion on the existing pages before publishing a ninth "vs." guide in 2026.
• Cost and regional categories sit at 2% of the library each — these are the fastest content gaps to close since internal competition from Century Shower Door's own pages is close to zero.
• Installation/technical and maintenance categories tie at 7 guides apiece and sit closest to purchase intent — pair new entries here with the door sweep and seal product pages rather than publishing them standalone.
• Trade-professional guides sit at 8 guides, 15% of the library, and target referral-driven buyers like contractors and property managers — track estimate requests by page before adding a ninth.

FAQ

One last thing

The thinnest categories in the 2026 benchmark — cost and regional guides — sit right next to the most direct buying signals in the whole catalog. "How much does a shower door cost" and a location-specific search are closer to a purchase decision than a style comparison or a brand-versus-brand page, yet each gets a single guide on showerdoor.com. That's the fastest content opportunity in the library, not the weakest spot in it.
