What Dallmer does
Dallmer GmbH + Co. KG is a German family-owned manufacturer of professional drainage technology founded in 1913 and headquartered in Arnsberg, Germany. The company designs and produces a comprehensive portfolio of drainage solutions for residential and commercial buildings, organized around three modular system families: the DallFlex shower channel platform (with variants CeraWall, CeraFloor, Zentrix, CeraNiveau, CeraFrame, and CeraFrame Liquid Neo), the DallDrain floor drain system (with CeraDrain and modular Series 10/15 components), and specialty drainage for cellar, roof, and balcony applications including the SuperDrain siphonic roof drainage line. Supporting the core product portfolio are anti-flooding valves (Stausafe, DallSafe), air-admittance valves (DallVent), traps, and an emerging Connect active drainage line that adds connected monitoring to selected shower channel variants. All products are designed to comply with DIN EN 1253-6 and -7 standards and integrate waterproofing, fire insulation, and sound insulation requirements, carrying a 10-year warranty.
Dallmer serves a B2B customer base primarily composed of architects and planners (who specify drainage systems in new construction and renovation projects), plumbers and installers (who execute the installation), and end homeowners (in the design and renovation segment). The company operates a horizontal segmentation approach, addressing use cases including barrier-free bathroom design, bathroom refurbishment, cellar waterproofing, roof and balcony drainage, anti-flooding protection, and plumbing ventilation. Go-to-market is built around a professional B2B channel strategy: the company engages specifiers through trade shows (architect@work, GET NORD), technical seminars, BIM files and DXF drawings, online configurators, and email newsletters, while distribution to end projects is handled through an international partner and reseller network spanning Germany, the United Kingdom, France, Spain, Poland, Switzerland, and Belgium, supplemented by direct regional sales contacts. Pricing is not publicly disclosed and is handled on a quote basis.
The business operates as a privately held GmbH + Co. KG, a structure common to German family-owned Mittelstand companies, with no public listing, external investors, or disclosed parent company. With 101-250 employees and over a century of operating history, Dallmer is a mature specialty manufacturer with a stable multi-country European footprint, sustained product innovation around its modular platform architecture, and an emerging extension into connected/smart drainage variants.

Dallmer competitors and assessment
Company assessmentBroad incumbents
- Geberit: Geberit is a large European sanitary technology group offering installation systems, cisterns, and bathroom drainage — overlapping with Dallmer's trap, shower channel, and air-admittance valve categories at much larger scale.
- Viega: Viega manufactures plumbing, drainage, and pipe-joining systems across residential and commercial buildings, including shower channels and floor drains that overlap with Dallmer's core range.
- Hansgrohe: Hansgrohe is a major German shower and bathroom fittings brand; while primarily focused on taps and showers, it competes for the same architect-driven specification wallet and bathroom renovation budgets as Dallmer.
Direct peers
- Kessel AG: Kessel is a German specialist in building drainage, backwater protection, and roof drains — directly comparable to Dallmer's Stausafe anti-flooding valves and SuperDrain siphonic roof drainage lines.
- HL Hutterer & Lechner: HL is an Austrian manufacturer of floor drains, shower channels, and building drainage products with strong DACH-region presence, making it a direct niche competitor to Dallmer.
- Blücher (Watts Water Technologies): Blücher produces stainless steel floor drains, channels, and roof drainage for commercial and residential applications, competing directly with Dallmer's modular floor and shower drain systems.
- ACO Drainage Systems: ACO is a leading European manufacturer of drainage systems for buildings, civil infrastructure, and bathrooms, directly competing with Dallmer's shower channel, floor drain, and roof drainage portfolios.
- TECE: TECE produces installation and drainage systems for bathrooms, including shower channels and drain bodies, and competes head-to-head with Dallmer's DallFlex and DallDrain platforms in the German-speaking market.
Emerging players
- Wedi GmbH: Wedi manufactures modular bathroom systems including shower elements with integrated drainage, overlapping with Dallmer's level-access shower solutions from a system-selling perspective.
- Joco Bespoke (and similar design drainage brands): Smaller design-led shower channel and linear drain brands targeting high-end residential and architectural projects, competing with Dallmer's CeraLine, TistoLine, and CeraWall premium offerings.
