# Prime-Line M6258 Shower Door Seal *Published: 2026-09-27 | Updated: 2026-09-27 | Source: https://shopsavvy.com/products/prime-line-m6258-shower-door-seal* --- **Brand:** PRIME-LINE **Price Range:** $7.4 - $62.5 across 46 retailers ## Pros - Easy to install by measuring and cutting to the right length, making it user-friendly even for DIY newbies. - Replaces cracked or old seals effectively, improving water containment. - Slides into place with minimal effort, often only needing gentle taps or upward pressure. - Can be cut to size with a hacksaw or utility knife, allowing customization. - Helps eliminate water leaks by fitting tightly against the glass and shower base. - Made from durable vinyl, offering good longevity if properly fitted. - Looks attractive and modern when installed well. - Can be adjusted with fine sandpaper for a snug fit in tighter gaps. - Works well with shower doors that have around 1/2 to 5/8 inch gaps. - Suitable for replacing old, moldy, or discolored seals to improve bathroom appearance. ## Cons - Initially stiff material that becomes more flexible over time, which may require sanding or careful installation. - The product is made from a stiff acrylic blend, not silicone or rubber, which can limit flexibility. - Designed for very specific spacing (~1/16 inch or 2mm), limiting universal application. - The side lip is nearly as stiff as plexiglass, making it difficult to manipulate or bend into place initially. - Compatibility varies with door types—may not fit older metal framed doors or narrow gaps. - Some users reported inconsistent shipping, with sets arriving in fewer quantities or separately. - Not suitable as a spray or water containment training tool—more for actual leaks. - Difficult to slide fully across tight fit areas; often better to angle it from the bottom. - Some find the tight fit too difficult to install without sanding, especially on non-standard doors. - Overall performance can be disappointing if the fit isn't perfect, leading to water still escaping. ## Specifications | Attribute | Value | |-----------|-------| | ASIN | B00E4BI9NG | | Size | ‎1-(Pack) | | Colour | ‎Clear | | Finish | ‎Clear | | Sold by | — | | Material | ‎Vinyl | | Thickness | ‎0.38 Inches | | Item Weight | ‎0.28 g | | Part Number | ‎M 6258 | | Manufacturer | ‎Prime-Line Products | | Brand | Prime-Line | | Easy to clean | 1-(Pack) | | Colour | Clear | | Easy to install | ZESSA LTD | | Value for money | Vinyl | | Material | Vinyl | | Customer Ratings | 4.4 | | Customer Reviews | 4.4 out of 5 stars | ## About This Product Keep your bathroom looking great and free from water leaks with this M 6258 frameless shower door bottom seal. Made of clear vinyl material, it’s designed to attach to the bottom of frameless, swinging shower doors without adhesives. Use it to replace discolored and moldy shower door seals or leaky, unreliable seals. Installation takes just minutes and doesn’t require adhesives or other additional products. The shower door bottom seal fits a 3/8” x 36” swinging shower door, but can easily be cut to fit a shorter door with a hacksaw, tin snips or utility knife. The genuine Prime-Line part will have an insert showing "M-6258" & "Prime-Line" clearly printed on it. Some third party sellers are shipping a different version with a shorter fin. For alternate design, see also Prime-Line’s model number M-6264. ## Current Prices | Retailer | Price | Availability | |----------|-------|-------------| | [Abttvs](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/Pxhw3mSVDJB0dryCqWd0?source=shopsavvy&medium=product-page) | $7.40 | Check | | [My Store](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/mrO42PRuvWCeyaa2tGFR?source=shopsavvy&medium=product-page) | $7.40 | Check | | [My Store](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/8QAc1XjLMdkbYhs3jewI?source=shopsavvy&medium=product-page) | $7.40 | Check | | [My Store](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/0iHbAyybXdHMeackH0Ep?source=shopsavvy&medium=product-page) | $7.40 | Check | | [The Home Depot](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/5f2eead3-1d87-d3f6-3cdc-78c9e78ea83d?source=shopsavvy&medium=product-page) | $10.95 | Check | | [Amazon](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/d8c5df6c-5320-4868-8438-3e77354352bf?source=shopsavvy&medium=product-page) | $12.00 | Check | | [MSM](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/c2439611-2bfc-5dc7-4fa0-ca074bc90b74?source=shopsavvy&medium=product-page) | $12.89 | Check | | [Stine Lumber](https://shopsavvy.com/api/redirect/products/EbhN9r73zfbjnmxkgMkF/offers/9ef94efa-dbb6-4aac-23e2-a6b60d1a5e24?source=shopsavvy&medium=product-page) | $13.49 | Check | | [R.P.
