Bath sealing strip on a roll.
I fitted a new shower tray and after only a few months the black mold started to appear spoiling the new bathroom experience. I thought I would try a roll of bath sealer from Must Have Ideas. It arrived as promised and was east to apply. My shower is rejuvenated and I am so pleased. I am looking around for other uses of this wonderful product. I have no hesitation in recommending this product to friends and would use Must Have again.

Sealing strip
Prompt delivery and a great product. The sealer round our upvc back door kept splitting even though we replaced the sealant several times. This sealing strip was easy to use and looks good.

Simple Seal, quick, easy to fit and effective.
I bought Simple Seal to seal around my shower tray and to cover the stained grouting at the edge. It came with clear instructions and was very easy to fit. It's really freshed up the look of my bathroom.. I also used it to smarten up a corner in my downstairs toilet after a wall was replastered. Delivery was very quick. I can certainly recommend.

So easy to use. It's brilliant.
Fast delivery, easy to use, put along kitchen worktop around whole kitchen, looks fresh easy to clean splashes from sink. Loved it so much put along bathroom floor which has tiles, this gives it a much better finished look. Highly recommend.

I have ordered quite a lot recently - a very happy customer!
I have ordered quite a lot this last few weeks and I must say I am extremely happy with my products. I ordered Skirting board buddy - love this no more bending down, hurting my knees and back, comes with 2 clothes. Absorbe it all cloths - wow, soaks up so much liquid and no drips wow! Brilliant for windows Simple seal ( yet to use ) Honey comb heaven - fabulous Fresher for longer bags - still looking fresh Sumo strips - great product, no damage to wall when I changed my mind where to put the pictures Germ free genie - no disgusting toilet water drips Grow gloves - will be trying these out thus weekend fit well excited to use. No more broken nails. Wollen wonders - worked really well although I would just point out, I didn't use with my dark washing as fibres come off. Data defender - no more time consuming ripping up of paper. Better brush long handle broom and small handle - great, attracts all the cat hairs but doesn't get clogged in the bristle like my old one. I have my eye on some more items so will be ordering again! Delivery prompt and communications superb well done, keep up the good work! Also they sent me a further 20% off voucher, happy days One very happy customer

A company which has a good variety of useful items and gives helpful and friendly service.
I’ve only recently started to purchase from this company and so far I’m very happy with items and service received. My favourites are the Bright Bars which are both useful and decorative, give off a really bright light useful for dark corners and are attractive placed on an internal staircase, the Mould Magic Extreme was easy to use and worked very effectively removing black mould from old veluxe window frames, the Simple Seal used along the back of my bath has tidied up the join between my bath and tiles, the Wonder Wrap bags have made wrapping Christmas gifts so much easier saving my old arthritic fingers a lot of time and pain, and the microfibre cloths are excellent for dusting and general cleaning. I haven’t quite got the knack of the Sumo Strip yet, I found it tricky to separate the backing tape from the sticky side but hopefully will get help with that from my nephew. In all it’s a company worth looking out for and I highly recommend it. Helpful and friendly too.

Great product
Great product. Much easier to apply than sealant from a tube. Loved the helpful leaflet with tips on melting the glue so it stuck better. Looks a really professional job. Easy to wipe down after a shower as well.
