美国采购需求：马桶刷、马桶清洁剂、台盆、台面盆、浴室擦手巾、亚克力淋浴盘

I'm looking for assistance regarding a toilet seat replacement for my elongated toilet from SSWw. The current seat has become discolored, and I'm hoping to find a suitable replacement. However, it appears that the seat dimensions may not align with standard sizes on the market, which complicates things a bit. Could you please let me know if it's possible to purchase just the lid for this elongated model? I'm specifically interested in finding an option that fits without needing to replace the entire seat. Any information you can provide on this would be greatly appreciated. Thank you!
