\u2757 Case Study: Shower Enclosure Sold as \u201c900mm\u201d but Unable to Fit a 900mm Opening Against – heatandplumb.com<\/h1>\n

Author:<\/strong> Andreas RUsso
\nDate:<\/strong> 28th Jan 2026
\nLocation:<\/strong> United Kingdom<\/p>\n

\n

1. Background<\/h2>\n

I purchased a bi-fold shower enclosure from a UK retailer, advertised and sold online as a 900mm shower enclosure<\/strong>.<\/p>\n

The product listing clearly shows a selectable option labelled:<\/p>\n

900mm x 700mm \u2013 5mm Glass<\/strong><\/p><\/blockquote>\n

This enclosure was purchased specifically for installation onto a standard 900mm shower tray<\/strong>, which is one of the most common sizes used in UK residential properties.<\/p>\n

This article documents the measurements, correspondence, and delays encountered when the product was found to be physically incapable of fitting a 900mm opening<\/strong>.<\/p>\n

\n

\"\"<\/h2>\n

2. What the Website Claims<\/h2>\n

At the point of sale, the retailer\u2019s website presents the enclosure as a 900mm product<\/strong>, without any prominent warning that it may not actually reach 900mm in real-world installation.<\/p>\n

A reasonable consumer would naturally understand \u201c900mm\u201d to mean:<\/p>\n

    \n
  • Suitable for a 900mm opening<\/strong><\/li>\n
  • Compatible with a 900mm tray<\/strong><\/li>\n
  • Capable of being installed without leaving a gap<\/li>\n<\/ul>\n

    This expectation is entirely reasonable and consistent with standard bathroom product marketing.<\/p>\n

    \n

    3. What Happens in Reality<\/h2>\n

    Once delivered and installed, the enclosure was extended to its maximum possible adjustment<\/strong> using the supplied wall profiles.<\/p>\n

    Despite this:<\/p>\n

      \n
    • La maximum achievable width<\/strong> was approximately 870\u2013885mm<\/strong><\/li>\n
    • The enclosure could not span a 900mm opening<\/strong><\/li>\n
    • A visible and unacceptable gap remained<\/strong><\/li>\n<\/ul>\n

      This was confirmed using multiple tape-measure photographs showing the enclosure already at full extension.<\/p>\n

      In short:<\/p>\n

      A product sold as 900mm cannot physically reach 900mm.<\/strong><\/p><\/blockquote>\n

      \"\" \"\" \"\" \"\" \"\" \"\"<\/p>\n

      \n

      4. Evidence Supplied<\/h2>\n

      The following evidence was provided to the retailer:<\/p>\n

        \n
      • Photographs of the enclosure fully extended<\/strong><\/li>\n
      • Clear tape-measure readings showing 850-885<\/li>\n
      • Images demonstrating that the profiles were already set to their maximum adjustment<\/strong><\/li>\n
      • Confirmation that no further extension was possible<\/li>\n<\/ul>\n

        This evidence directly addresses the only relevant technical question:
        \nWhat is the maximum width the enclosure can achieve?<\/strong><\/p>\n

        \n

        5. Inconsistent Statements and Changing Specifications<\/h2>\n

        During correspondence, multiple and conflicting adjustment ranges were stated:<\/p>\n

          \n
        • Initially: 850\u2013885mm<\/strong><\/li>\n
        • Later: Up to 890mm<\/strong><\/li>\n
        • Later still: 870mm is within tolerance<\/strong><\/li>\n<\/ul>\n

          At no point does any of these figures reach 900mm<\/strong>, despite the product being sold as such.<\/p>\n

          These inconsistencies created confusion and prolonged the process unnecessarily.<\/p>\n

          \n

          6. Moving the Goalposts: How Resolution Was Delayed<\/h2>\n

          Rather than resolving the issue once the dimensional shortfall was shown, new requirements were repeatedly introduced<\/strong>.<\/p>\n

          Examples include:<\/p>\n

            \n
          • Requesting additional photographs after clear measurements were already supplied<\/li>\n
          • Asking for tray measurements, despite the issue relating to the enclosure\u2019s maximum width<\/strong>, not the tray<\/li>\n
          • Stating that images were \u201cunclear\u201d despite visible tape measurements<\/li>\n
          • Repeatedly referring the matter back to the manufacturer without reaching a conclusion<\/li>\n<\/ul>\n

            Each time evidence was provided, the basis for acceptance changed<\/strong>.<\/p>\n

            This pattern is commonly described as \u201cmoving the goalposts\u201d<\/strong> \u2014 where compliance with one request simply results in another request, delaying a decision without addressing the core issue.<\/p>\n

             <\/p>\n

            The problem is not measurement confusion anymore \u2014 it\u2019s the seller moving the goalposts to delay a replacement.<\/strong><\/p>\n

            \n

            2. Why the supplier is stalling (what\u2019s really happening)<\/h2>\n

            They are doing 3 classic delay tactics<\/strong>:<\/p>\n

            \ud83d\udd34 Tactic 1: Contradicting their own specs<\/h3>\n
              \n
            • First: \u201c850\u2013885mm\u201d<\/li>\n
            • Then: \u201cUp to 890mm\u201d<\/li>\n
            • Then: \u201c870mm is within range\u201d<\/li>\n
            • Now: \u201cWe can\u2019t tell from the images\u201d<\/li>\n<\/ul>\n

              \ud83d\udc49 This inconsistency alone proves misrepresentation<\/strong>.<\/p>\n

              \n

              \ud83d\udd34 Tactic 2: Asking for irrelevant measurements<\/h3>\n

              They are now asking you to:<\/p>\n

                \n
              • Measure the tray<\/strong><\/li>\n
              • Show profile extension kits<\/strong><\/li>\n
              • Remove \/ re-show the entire frame<\/strong><\/li>\n<\/ul>\n

                This is irrelevant<\/strong>, because:<\/p>\n

                  \n
                • La product max width is fixed<\/strong><\/li>\n
                • La gap exists regardless of tray size<\/strong><\/li>\n
                • The issue is the door cannot reach 900mm<\/strong><\/li>\n<\/ul>\n

                  They are fishing for any excuse<\/em> not to replace.<\/p>\n

                  \n

                  \ud83d\udd34 Tactic 3: Saying the images are \u201cunclear\u201d<\/h3>\n

                  This is a standard evidence rejection tactic<\/strong>.<\/p>\n

                  However:<\/p>\n

                    \n
                  • Your images clearly show the tape<\/strong><\/li>\n
                  • The numbers are visible<\/strong><\/li>\n
                  • The installer\u2019s hands are holding the frame at max extension<\/li>\n<\/ul>\n

                    They are not confused<\/strong> \u2014 they are avoiding approval from the manufacturer<\/strong>.<\/p>\n

                     <\/p>\n

                    \n

                    7. Why Further Measurements Do Not Change the Outcome<\/h2>\n

                    A framed shower enclosure has a fixed design limit<\/strong>.<\/p>\n

                    Once extended to its maximum:<\/p>\n

                      \n
                    • The width cannot be increased further<\/li>\n
                    • Measuring the tray again does not change the enclosure\u2019s dimensions<\/li>\n
                    • Profile extensions cannot compensate for a 15\u201330mm structural shortfall<\/strong><\/li>\n<\/ul>\n

                      Further requests for measurements or images do not resolve the issue \u2014 they only postpone a straightforward decision.<\/p>\n

                      \n

                      8. The Simple Solution Being Delayed<\/h2>\n

                      This matter can be resolved easily.<\/p>\n

                      The options are clear:<\/p>\n

                        \n
                      1. Supply a correctly sized replacement enclosure<\/strong> that genuinely fits a 900mm opening
                        \no<\/li>\n
                      2. Issue a full refund<\/strong>, including return costs<\/li>\n<\/ol>\n

                        No further technical investigation is required to reach this conclusion.<\/p>\n

                        \n

                        9. Consumer Rights Position (UK)<\/h2>\n

                        Under the Consumer Rights Act 2015<\/strong>, goods must be:<\/p>\n

                          \n
                        • As described<\/li>\n
                        • Fit for purpose<\/li>\n
                        • Of satisfactory quality<\/li>\n<\/ul>\n

                          A shower enclosure marketed and sold as 900mm<\/strong>, but unable to reach 900mm in practice, fails these requirements.<\/p>\n

                          \n

                          10. Conclusion<\/h2>\n

                          This case highlights a common issue in bathroom product retail:<\/p>\n

                            \n
                          • Nominal sizes being advertised without matching real-world capability<\/li>\n
                          • Inconsistent specifications<\/li>\n
                          • Delays caused by repeated, shifting requests for evidence<\/li>\n<\/ul>\n

                            The issue here is not installation, misunderstanding, or lack of information.<\/p>\n

                            It is a simple dimensional mismatch between what was sold<\/strong> y what was supplied<\/strong>.<\/p>\n

                            A prompt replacement or refund would resolve the matter immediately.<\/p>\n

                            \n
